THE MENTAL TRAITS OF BIRDS
In comparison with mammalian mentality, the avian mind is much
more elementary and primitive. It is as far behind the average of
the mammals as the minds of fishes are inferior to those of
reptiles.
Instinct Prominent in Birds. The average bird is more a creature
of instinct than of reason. Primarily it lives and moves by and
through the knowledge that it has inherited, rather than by the
observations it has made and the things it has thought out in its
own head.
But let it not for one moment be supposed that the instinctive
knowledge of the bird is of a mental quality inferior to that of
the mammal. The difference is in kind only, not in degree. As a
factor in self-preservation the keen and correct reasoning of the
farm-land fox is in no sense superior to the wonderful instinct
and prescience of the golden plover that, on a certain calendar
day, or week, bids farewell to its comfortable breeding-grounds in
the cold north beyond the arctic circle, rises high in the air and
launches forth on its long and perilous migration flight of 8,000
miles to its winter resort in Argentina.
The Migrations of Birds. Volumes have been written on the
migrations of birds. The subject is vast, and inexhaustable. It
is perhaps the most wonderful of all the manifestations of avian
intelligence. It is of interest chiefly to the birds of the
temperate zone, whose summer homes and food supplies are for four
months of the year buried under a mantle of snow and ice. All but
a corporal's guard of the birds of the United States and Canada
must go south every winter or perish from starvation and cold. It
is a case of migrate or die. Many of the birds do not mind the
cold of the northern winter—if it is dry; and if they could be
fed in winter, many of them would remain with us throughout
the year.
Consider the migratory habits of our own home favorites,
and see what they reveal. After all else has been said, bird
migration is the one unfathomable wonder of the avian world.
Really, we know of it but little more than we know of the songs of
the morning stars. We have learned when the birds start; we know
that many of them fly far above the earth; we know where some of
them land, and the bird calendars show approximately when they
will return. And is not that really about all that we do
know?
[Illustration with caption: MIGRATION OF THE GOLDEN PLOVER From
"Bird Migration,", by Dr. W. W. Cooke, U. S. Department of
Agriculture, 1915.]
What courage it must take, to start on the long, tiresome and
dangerous journey! How do they know where to go, far into the
heart of the South, to find rest, food and security? When and
where do they stop on the way to feed? Vast areas are passed over
without alighting; for many species never are seen in mid career.
Why is it that the golden plover feels that it is worth while to
fly from the arctic coast to Argentina?
Let any man—if one there be—who is not profoundly impressed by
the combined instinct and the reasoning of migratory birds do
himself the favor to procure and study the 47-page pamphlet by Dr.
Wells W. Cooke, of the U. S. Department of Agriculture, entitled
"Bird Migration." I wish I could reproduce it entire; but since
that is impossible, here are a few facts and figures from it.
The Bobolink summers in the northern United States and southern
Canada, and winters in Paraguay, making 5000 miles of travel each
way.
The Scarlet Tanager summers in the northeastern quarter of the
United States and winters in Colombia, Equador and northern Peru,
a limit to limit flight of 3,880 miles.
The Golden Plover (Charadrius dominicus).—"In fall it
flies over the ocean from Nova Scotia to South America, 2,400
miles—the longest known flight of any bird. In spring it returns
by way of the Mississippi Valley. Thus the migration routes form
an enormous ellipse, with a minor axis of 2,000 miles and a major
axis stretching 8,000 miles from arctic America to Argentina."
(Cooke.) The Arctic Tern (Sterna paradisaea), is "the
champion long-distance migrant of the world. It breeds as far
north as it can find land on which to build its nest, and winters
as far south as there is open water to furnish it food. The
extreme summer and winter homes are 11,000 miles apart, or a
yearly round trip of 22,000 miles." (Cooke.)
By what do migrating birds guide their courses high in air on a
pitch-dark night,—their busy time for flying? Do they, too, know
about the mariner's Southern Cross, and steer by it on starlit
nights? Equally strange things have happened.
The regular semi-annual migrations of birds may fairly be regarded
as the high-water mark of instinct so profound and far-reaching
that it deserves to rank as high as reason. To me it is one of the
most marvelous things in Nature's Book of Wonders. I never see a
humming-bird poised over a floral tube of a trumpet creeper
without pausing, in wonder that is perpetual, and asking the
eternal question: "Frail and delicate feathered sprite, that any
storm-gust might dash to earth and destroy, and that any enemy
might crush, how do you make your long and perilous
journeys unstarved and unkilled? Is it because you bear a charmed
life? What is the unsolved mystery of your tiny existence in this
rough and cruel world?"
We understand well enough the foundation principles of mammalian
and avian life, and existence under adverse circumstances. The
mammal is tied to his environment. He cannot go far from the
circumpolar regions of his home. A bear chained to a stake is
emblematic of the universal handicap on mammalian life. Survive or
perish, the average land-going quadruped must stay put, and make
the best of the home in which he is born. If he attempts to
migrate fast and far, he is reasonably certain to get into grave
danger, and lose his life.
The bird, however, is a free moral agent. If the purple grackle
does not like the sunflower seeds in my garden, lo! he is up and
away across the Sound to Oyster Bay, Long Island, where his luck
may be better. Failing there, he gives himself a transfer to
Wilmington, or Richmond, via his own Atlantic coast line.
The wonderful migratory instincts of birds have been developed
and intensified through countless generations by the imperative
need for instinctive guidance, and the comparatively small
temptation to inductive reasoning based on known facts. Evidently
the bird is emboldened to migrate by the comfortable belief that
somewhere the world contains food and warmth to its liking, and
that if it flies fast enough and far enough it will find it.
As a weather prophet, the prescience of the bird is strictly
limited. The warm spells of late February deceive the birds just
as they do the flowers of the peach tree and the apple. Often the
bluebirds and robins migrate northward too early, encounter
blizzards, and perish in large numbers from snow, sleet, cold and
hunger.
The Homing Sense of Birds. We can go no farther than to say that
while the homing instinct of certain species of birds is quite
well known, the mental process by which it functions is
practically unknown. The direction instinct of the homing pigeon
is marvelous, but we know that that instinct does not leap full-
fledged from the nest. The homer needs assistance and training.
When it is about three months old, it is taken in a basket to a
point a mile distant from its home and liberated. If it makes good
in returning to the home loft, the distances are increased by easy
stages—two, three, five, ten, twenty, thirty, fifty and seventy-
five miles usually being flown before the bird is sent as far as
100 miles. The official long-distance record for a homing pigeon
is 1689.44 miles, held by an American bird.
The homing instinct, or sense, is present in some mammals, but it
is by no means so phenomenal as in some species of birds. In
mammals it is individual rather than species-wide. Individual
horses, dogs and cats have done wonderful things under the
propulsion of the homing instinct, but that instinct is by no
means general throughout those species. Among wild animals,
exhibitions of the home-finding instinct are rare, but the annals
of the Zoological Park contain one amusing record.
For emergency reasons, a dozen fallow deer once were quartered in
our Bison range, behind a fence only sixty-six inches high.
Presently they leaped out to freedom, disappeared in the thick
northern forests of the Bronx, and we charged them up to profit
and loss. But those deer soon found that life outside our domain
was not the dream of paradise that they had supposed. After about
a week of wandering through a cold, unsympathetic and oatless
world those were sadder and wiser deer, and one night they all
returned and joyously and thankfully jumped back into their range,
where they were happy ever after.
Recognition of Sanctuary Protection. In this field of precise
observation and reasoning, most birds,—if not indeed all of
them,—are quick in discernment and accurate in deduction. The
great gauntlet of guns has taught the birds of the United States
and Canada to recognize the difference between areas of shooting
and no shooting. Dull indeed is the bird mind that does not know
enough to return to the feeding-ground in which it has been safe
from attack. The wild geese and ducks are very keen about
sanctuary waters, and no protected pond or river is too small to
command attention. Our own little Lake Agassiz, in the New York
Zoological Park, each year is the resort of hundreds of mallards
and black ducks. And each year a number of absolutely wild wood
ducks breed there and in spite of all dangers rear their young.
Our wild-fowl pond, surrounded by various installations for birds,
several times has been honored by visiting delegations of wild
geese, seven of which were caught in 1902 for exhibition.
The most astounding example of avian recognition of protection
and human friendship is the spectacle of Mr. Jack Miner's wild
goose sanctuary at Kingsville, Ontario, not far from Detroit. With
his tile works on one side and his home on the other, he scooped
out between them clay for his factory and made a small pond. With
deliberate and praiseworthy intention Mr. Miner planted there a
little flock of pinioned wild Canada geese, as a notice of
sanctuary and an invitation to wild flocks to come down for food,
rest and good society.
Very slowly at first the wild geese began to come; but finally the
word was passed along the line from Hudson Bay to Currituck Sound
that Miner's roadhouse was a good place at which to stop. Year by
year the wild geese came, and saw, and were conquered. So many
thousands came that presently Mr. Miner grew tired of spending out
of his own pocket more than $700 a year for goose corn; and then
the Canadian government most commendably assumed the burden, and
made Mr. Miner's farm a national bird preserve. [Footnote: Mr.
Miner is writing his wild-goose story into a book: and the story
is worth it!]
The annals of wild life protection literature contain many records
and illustrations of the remarkable quickness and thoroughness of
sanctuary recognition by birds. On the other hand I feel greatly
annoyed by the failure of waterfowl to reason equally well
regarding the decoys of duck-shooters. They fail to learn, either
by experience or hearsay, that small flocks of ducks sitting
motionless near a shore are loaded, and liable to go off. They
fail to learn that it is most wise to settle well outside such
flocks of alleged ducks, and that it is a fatal mistake to plump
down on the top of a motionless bunch.
Protective Association of Wasps and Caciques. The colonizing
caciques, of South America, representing four genera, are very
solicitous of the safety of their colonies. In numerous cases,
these colonies are found in association with wasps, one or more
nests invariably being found near the nests of the birds. It is
natural to infer that this strange association is due to the
initiative of the birds. When monkeys attack the birds, the birds
need the stinging insects.
As usual in the study of wild creatures, the first thing that we
encounter in the wild bird is
Temperament. On this hangs the success or failure of a species in
association with man. Temperament in the most intellectual wild
creatures is just as evident and negotiable to the human eye as
colors are in fur or feathers.
A vastly preponderating number of bird species are of sanguine
temperament; and it is this fact alone that renders it possible
for us to exhibit continuously from 700 to 800 species of birds.
Sensible behavior in captivity is the one conspicuous trait of
character in which birds mentally and physically are far better
balanced than mammals. But few birds are foolishly nervous or
hysterical, and when once settled down the great majority of them
are sanguine and philosophical. Birds of a great many species can
be caught in an adult state and settled down in captivity without
difficulty; whereas all save a few species of mammals, when
captured as adults, are irreconcilable fighters and many of them
die far too quickly. In a well-regulated zoological park nearly
every animal that has been caught when adult is a failure and a
nuisance.
To name the species of birds that can be caught fully grown and
settled down for exhibition purposes, would create a list of
formidable length. It is indeed fortunate for us that this is
true; for the rearing of nestlings is a tedious task.
A conspicuous exception to the rule of philosophic sedateness in
newly caught birds is the loon, or great northern diver. That bird
is so exceedingly nervous and foolish, and so persistent in its
evil ways, that never once have we succeeded in inducing a loon to
settle down on exhibition and be good. When caught and placed in
our kind of captivity, the loon goes daft. It dives and dives, and
swims under water until it is completely exhausted; it loses its
appetite, and very soon dies. Of course if one had a whole marine
biological station to place at the disposal of the foolish loon,
it might get on.
There are other odd exceptions to the rule of normal bird conduct.
Some of our upland game birds, particularly the Franklin grouse
and ptarmigan of the Rocky Mountains, display real mental
deficiencies in the very necessary business of self-preservation.
WILDNESS AND TAMENESS OF THE RUFFED GROUSE. The ruffed grouse is
one of the most difficult of all North American game birds to keep
in captivity. This fact is due largely, though not entirely, to
the nervous and often hysterical temperament of this species. Some
birds will within a reasonable time quiet down and accept
captivity, but others throughout long periods,—or forever,—
remain wild as hawks, and perpetually try to dash themselves to
pieces against the wire of their enclosures. Prof. A. A. Allen of
Cornell once kept a bird for an entire year, only to find it at
the end of that time hopelessly wild; so he gave the bird its
liberty.
However, in this species there are numerous exceptions. Some wing-
tipped birds have calmed down and accepted captivity gracefully
and sensibly, and a few of the cases of this kind have been
remarkable. The most astonishing cases, however, have been of the
tameness of free wild birds, in the Catskills, and also near the
city of Schenectady. A great many perfectly truthful stories have
been published of wild birds that actually sought close
acquaintance with people, and took food from their hands.
We have been asked to account for those strange manifestations,
but it is impossible to do so. It seems that in some manner,
certain grouse individuals learned that Man is not always a killer
and a dangerous animal, and so those birds accepted him as a
friend,—until the killers came along and violated the sanctuary
status.
It is both necessary, and highly desirable for the increase of
species, that all wild birds should fly promptly, rapidly and far
from the presence of Man, the Arch Enemy of Wild Life. The species
that persistently neglects to do so, or is unable, soon is utterly
destroyed. The great auk species was massacred and extirpated on
Funk Island because it could not get away from its sordid enemies
who destroyed it for a paltry supply of oil.
The Fool Hen and Its Folly. In our own country there exists a
grouse species so foolish in its mind, and so destitute of the
most ordinary instinct of self-preservation that it has been known
for many years as "the Fool Hen." Definitely, it is the Franklin
Grouse (Conachites franklini), and its home is in the
foothills of the Rocky Mountains. This famous and pitiable victim
of misplaced confidence will sit only eight feet up on a jack pine
limb, beside a well travelled road, while Mack Norboe dismounts,
finds a suitable stick, and knocks the foolish bird dead from its
perch. I have seen these birds sit still and patiently wait for
their heads to be shot off, one by one, with a .22 calibre
revolver when all points of the compass were open for their
escape.
All this, however, must be set down as an unusual and phenomenal
absence of the most natural instinct of self-protection. The
pinnated grouse, sage grouse, Bob White quail and ptarmigan
exercise but little keen reason in self-protection. They are easy
marks,—the joy of the pot-hunter and the delight of the duffer
"sportsman."
Dullness of Instinct in Grouse and Quail. The pinnated grouse,
which in Iowa and the Dakotas positively is a migratory bird, does
know enough to fly high when it is migrating, but seemingly this
species and the sage grouse never will grow wise enough to save
themselves from hunters when on their feeding grounds. In
detecting the presence of their arch enemy they are hopelessly
dull; and they are slow in taking wing.
The quail is a very good hider, but a mighty poor flyer. When a
covey is flushed by a collection of dogs and armed men, the
lightning-quick and explosive get-away is all right; but the
unshot birds do not fly half far enough! Instead of bowling away
for two or three miles and getting clear out of the danger zone
and hiding in the nearest timber, what do they do? They foolishly
stop on the other side of the field, or in the next acre of brush,
in full view of the hunters and dogs, who find it great fun to
hustle after them and in fifteen minutes put them up again. Thus
it is easy for a hunting party to "follow up" a covey until the
last bird of it has been bagged.
Just before the five-year close season on quail went into effect
in Iowa, this incident occurred:
On a farm of four hundred acres in the southern part of the state,
two gunners killed so nearly up to their bag limit of fifty
birds per day that in ten days they went away with 400 quail.
The foolish birds obstinately refused to leave the farm which had
been their home and shelter. Day after day the chase with dogs and
men, and the fusillade of shots, went briskly on. As a matter of
fact, that outfit easily could have gone on until every quail on
that farm had fallen.
It is indeed strange that the very bird which practices such fine
and successful strategy in leading an intruder away from its
helpless young, by playing wounded, should fail so seriously when
before the guns. A hunted quail covey should learn to post a
sentry to watch for danger and give the alarm in time for a safe
flight.
But I know one quail species that is a glorious exception. It is
Gambel's quail, of southern Arizona. I saw a good wing shot, Mr.
John M. Phillips, hunt that quail (without dogs) until he was hot
and red, and come in with more wrath than birds. He said, with an
injured air:
"The little beggars won't rise! I don't want to shoot them on the
ground, and the minute they rise above the creosote bushes they
drop right down into them again, and go on running."
It was even so. They simply will not rise and fly away, as Bob
White does, giving the sportsmen a chance to kill them, but when
forced to fly up clear of the bushes they at once drop back again.
[Footnote: A very few quail-killers of the East who oppose long
close seasons contend that quail coveys "breed better" when they
are shot to pieces every year and "scattered," but we observed
that the quail of the Sonoran Desert managed to survive and breed
and perpetuate themselves numerously without the benevolent
cooperation of the "pump-gun" and the automatic shotgun.] While
the study of avian mentality is a difficult undertaking, this is
no excuse for the fact that up to this date (1922) that field of
endeavor has been only scratched on its surface. The birds of the
world are by no means so destitute of ideas and inventions that
they merit almost universal neglect. Because of the suggestions
they contain we will point out a few prominent mental traits in
birds, chosen at random.
At the same time, let us all beware of seeing too much, and chary
of recording scientific hallucinations. It is better to see
nothing than to see many things that are not true! In ten octavo
pages that particular rock can split wide open the best reputation
ever grown.
Bird Architecture. The wisdom of birds in the selection of nesting
sites, the designing of the best nest for their respective wants,
and finally the construction of them, indicate instinct, reasoning
power and mechanical skill of a high order. The range from the
wonderful woven homes of the weaver bird and the Baltimore oriole
down to the bare and nestless incubating spot of the penguin is so
great that nothing less than a volume can furnish space in which
to set it forth. But let us at least take a brief glance at a wide
range of home-building activities by birds.
The orioles, caciques and weavers weave wonderful homes of fibrous
material, often in populous communities.
The bower birds erect remarkable bowers, as playhouses.
The brush turkey scratches together a huge mound of sticks and
leaves, four feet by ten or twelve wide at the base.
The vireo and many others turn out beautiful cup-like nests.
The hummingbird builds with the solidity and tenacity of the wasp.
The swallow is a wonderful modeler with mud.
The guacharo builds a solid nest like a cheese with a concave top.
The auklet, the puffin and the kingfishers burrow into the
friendly and solid earth. The eider duck plucks from its own breast
the softest, of feather linings for its nest.
[Illustration with caption: REMARKABLE
VILLAGE NESTS OF THE SOCIABLE WEAVER BIRD (Copied from "The Fauna
of South Africa Birds," by Arthur C. Stark)]
The grebe thoughtfully keeps its nest above high-water mark by
building on a floating island.
The murre and the guillemot do their best to escape their enemies
of the land by building high upon inaccessible rock ledges.
The woodpecker trusts no living species save his own, and drills
high up into a hollow tree-trunk for his home.
The cactus wren and crissal thrasher build in the geographical
centres of tree choyas, so protected by 500,000 spines that no
hawk or owl can reach them.
This catalogue could be extended to a great length; but why pile
evidence upon evidence!
It cannot be correct to assume that the nesting activities of
birds are based upon instinct alone. That theory would be
untenable. New conditions call for independent thought, and
originality of treatment. If the ancestral plans and
specifications could not be varied, then every bird would have to
build a nest just "such as mother used to make," or have no brood.
All bird students know full well how easily the robin, the wren,
the hawk and the owl change locations and materials to meet new
and strange conditions. A robin has been known to build on the
running-board of a switch-engine in a freight yard, and another
robin built on the frame of the iron gate of an elephant yard. A
wren will build in a tin can, a piece of drain tile, a lantern, a
bird house or a coat pocket, just as blithely as its grandmother
built in a grape arbor over a kitchen door. All this is the hall
mark of New Thought.
Whenever children go afield in bird country, they are constantly
on the alert for fresh discoveries and surprises in bird
architecture. Interest in the nest-building ingenuity and
mechanical skill of birds is perpetual. The variety is almost
endless. Dull indeed is the mind to which a cunningly contrived
nest does not appeal. Tell the boys that it is all right to
collect abandoned nests, but the taking of eggs and
occupied nests is unlawful and wicked.
The Play-House of the Bower Bird. Years ago we read of the
wonderful playhouses constructed by the bower birds of Australia
and New Guinea, but nothing ever brought home to us this
remarkable manifestation of bird thought so closely as did the
sight of our own satin bower bird busily at work on his own bower.
He was quartered in the great indoor flying cage of our largest
bird house, and supplied with hard grass stems of the right sort
for bower-making.
With those materials, scattered over the sand floor, the bird
built his bower by taking each stem in his beak, holding it very
firmly and then with a strong sidewise and downward thrust
slicking it upright in the sand, to stand and to point "just
exactly so." The finished bower was a Gothic tunnel with walls of
grass stems, about eighteen inches long and a foot high. In making
it the male bird wrought as busily as a child building a playhouse
of blocks. Our bird would pick up pieces of blue yarn that had
been placed in his cage to test his color sense, but never red,—
which color seemed to displease him. As the bird worked quietly
yet diligently, one could not help longing to know what thoughts
were at work in that busy little brain.
The most elaborate of all the bower bird play-houses is that
constructed by the gardener bower bird, which is thus described by
Pycraft in his "History of Birds":
"This species builds at the foot of a small tree a kind of hut or
cabin, some two feet in height, roofed with orchid stems that
slope to the ground, regularly radiating from the central support,
which is covered with a conical mass of moss sheltering a gallery
round it. One side of this hut is left open, and in front of it is
arranged a bed of verdant moss, bedecked with blossoms and berries
of the brightest color. As the ornaments wither they are removed
to a heap behind the hut and replaced by others that are fresh.
The hut is circular and some three feet in diameter, and the mossy
lawn in front of it is nearly twice that expanse. Each hut and garden
is believed to be the work of a single pair of birds. The use of the
hut, it appears, is solely to serve the purpose of a playing-ground,
or as a place wherein to pay court to the female, since it, like the
bowers built by its near relatives, are built long before the nest
is begun, this, by the way, being placed in a tree."
[Illustration with caption: SPOTTED BOWER-BIRD, AT WORK ON ITS
UNFINISHED BOWER Foreground garnished with the bird's playthings.

Most Birds Fear Man. With the exception of those that have been
reared in captivity, nearly all species of wild birds, either in
captivity or out of it, fear the touch of man, and shrink from
him. The birds of the lawn, the orchard and the farm are always
suspicious, always on the defensive. But of course there are
exceptions. A naturalist like J. Alden Loring can by patient
effort win the confidence of a chickadee, or a phoebe bird, and
bring it literally to his finger. These exceptions, however, are
rare, but they show conclusively that wild birds can be educated
into new ideas.
The shrinking of wild birds from the hand of man is almost as
pronounced in captivity as it is in the wilderness, and this fact
renders psychological experiments with birds extremely difficult.
It is really strange that the parrots and cockatoos all should
take kindly to man, trust him and even like him, while nearly all
other birds persistently fly, or run, or swim or dive away from
him. A bird keeper may keep for twenty years, feeding daily, but
his hawks, owls and eagles, the perchers, waders, swimmers and
upland game birds all fly from him in nervous fear whenever he
attempts to handle them. The exceptions to this rule, out of the
20,000 species of the birds of the world, are few.
Wild Birds that Voluntarily Associate with Man. The species that
will do so are not numerous, and I will confine myself to some of
those that I have seen.
The Indian adjutant, the mynah, hoopoe, vulture, robin, phoebe
bird, bluebird, swallow, barn owl, flicker, oriole, jay, magpie,
crow, purple grackle, starling, stork, wood pigeon, Canada goose,
mallard, pintail, bob white and a few other species have accepted
man at his face value and endeavored to establish with him a
modus vivendi. The mallard and the graylag goose are the ancestors
of our domestic ducks and geese. The jungle fowls have given us
the domestic chickens. The wild turkey, the pheasants, the guinea
fowl, the ostrich, the emu and the peacock we possess in
domestication unchanged.
Caged Wild Birds Quickly Appreciate Sanctuary. Mr. Crandall
reports that in the Zoological Park there have been many instances
of the voluntary return to their cages of wild birds that have
escaped from them. The following instances are cited, out of many
that are remembered:
A wild hermit thrush, only two weeks in captivity, escaped from an
outdoor cage. But he refused to leave the vicinity of his new
home, and permanent food supply. He lingered around for two or
three days, and finally a wise keeper opened the cage door when he
was near it, and at once he went in.
A magpie escaped from an outside cage, and for a week he lingered
around it unwilling to leave its vicinity. At last the other birds
of the cage were removed, the door was left open, and the magpie
at once went back home.
Bird Memory and Talk. Birds have few ways and means by which to
reveal their powers of memory. The best exhibits are made by the
talking parrots and cockatoos. The feats of some of these birds,
both in memory and expression, are really wonderful. The startling
aptness with which some parrots apply the language they possess
often is quite uncanny. Concerning "sound mimicry" and the
efforts of memory on which they are based, Mr. Lee S. Crandall,
Curator of Birds, has contributed the following statement of his
observations:
"Many birds, including practically all members of the parrot
tribe, many of the crows and jays, as well as mynas and starlings,
learn to repeat sounds, words and sentences. Ability varies with
both species and individuals. Certain species show greater
aptitude as a whole than other species, while there is a great
difference between individuals of the same species. "Gray
parrots are generally considered the most intelligent of their
tribe, and are especially apt at imitating sounds, such as running
water, whistles, etc. I have one at home which always answers a
knock with 'Come in.' Often he furnishes the knock himself by
pounding the perch with his bill, following it with 'Come in.'
Amazon parrots are especially good at tunes, some specimens being
able to whistle complicated airs and sometimes sing several verses
in a high, clear voice. Both grays and Amazons often talk with
great fluency, vocabularies having been reported of as many as one
hundred words. Often there seems to be intelligent association of
certain acts or conditions with corresponding sentences, these
sometimes occurring with singular patness.
"Hill mynahs, of the genus Eulabes, often talk as well as
parrots. The common introduced European starling often says a few
words quite clearly. I once knew a long-tailed glossy starling
(Lamprotornis caudatus) which shared an aviary with an
accomplished albino jackdaw. The starling had acquired much of the
jackdaw's repertoire, and the 'conversations' carried on between
the two birds were most amusing."
A raven in the Zoological Park says "Arthur," "Shut up," "All out"
and "Now look what's here" as perfectly as any parrot.
Listed in the order of their ability to learn and remember talk,
the important talking birds are as follows: African gray parrot,
yellow-headed Amazon, other Amazons, the hill mynahs, the
cockatoos, the macaws, and the various others previously
mentioned.
It is safe to assert that all migratory birds display excellent
powers of memory, chiefly by returning to their favorite haunts
after long absences.
Recognition of Persons. Mr. Crandall says there can be no doubt of
the ability of most birds to recognize individual persons. This is
seen in the smallest species as well as in the largest. He once
saw a bullfinch in the last stages of pneumonia and almost
comatose, show an instant reaction to the presence of an owner it
had not seen in weeks. Many birds form dislikes for individual
persons. This is especially noticeable in the parrot tribe. A
large male South American condor was friendly enough with two of
his keepers but would instantly attack any other keeper or other
person entering his enclosure, whether wearing the uniform or not.
With his two approved keepers he was gentleness itself.
Parasitic Nesting Habits. In the bird world there are a few
species whose members are determined to get something for nothing,
and to avoid all labor in the rearing of their offspring. This
bad habit is known of the Old World cuckoos, the American cow-
birds, the South American rice grackle (Cassidix), and
suspected in the pin-tail whydah (Vidua serena). It seems
to reach its highest point in the cuckoos. It is believed that
individuals lay their eggs only in the nests of species whose eggs
resemble their own. Apparently much skill and intelligence is
required for introducing parasitic eggs at the most favorable
moment. This is equally true of other parasites.
Curator Crandall has taken several eggs and young of the rice
birds from nests of two species of giant caciques in Costa Rica,
but never saw an adult Cassidix. It is considered a very
rare species, but probably is more sly than scarce. Young cuckoos
eject unwelcome nestlings shortly after hatching.
Daily contact with a large and varied collection of birds great
and small, gathered from every section of the habitable regions of
the earth, naturally produces in time a long series of interesting
cases of intelligence and behavior. Out of our total occurrences
and observations I will offer two that reveal original thought.
Good Sense of the Wedge-Tailed Eagle. In discussing bird
intelligence with Mr. Herbert D. Atkin, keeper of our Eagles
Aviary and the cranes and water birds in the Flying Cage, he
called to my attention two species of birds which had very much
impressed him. Afterward he showed me all that he described.
Keeper Atkin regards the wedge-tailed eagle, of Australia, as the
wisest species with which he has to deal. In the first place, all
four of the birds in that flock recognize the fact that he is a
good friend, not an enemy, and each day they receive him in their
midst with cheerful confidence and friendship. In the fall when
the time comes to catch them, crate them and wheel them half a
mile to their winter quarters in the Ostrich House, they do not
become frightened, nor fight against being handled, and submit
with commendable sense and appreciation.
The one thing on which the wedge-tailed eagle really insists when
in his summer quarters, is his daily spray bath from a hose. When
his keeper goes in to give the daily morning wash to the cage, the
eagles perch close above his head and screech and scream until the
spray is turned upon them. Then they spread their wings, to get it
thoroughly, and come out thoroughly soaked. When the spray is
merely turned upon their log instead of upon the birds as they
sit higher up, they fly down and get into the current wherever it
may be.
Memory of the Cereopsis Goose. Keeper Atkin also showed me an
instance of the wisdom of the cereopsis geese, from Van Diemens
Land, South Australia. During the winter those birds are kept in
the Wild-Fowl Pond; but in summer they are quartered in a secluded
yard of the Crane's Paddock, nearly half a mile away. Twice a year
these birds go under their own steam between those two enclosures.
When turned out of the Cranes' Paddock last November they at once
set out and walked very briskly southward up the Bird's Valley,
past the Zebra House. On reaching the Service Road, a quarter of a
mile away, they turned to the left and kept on to the Wolf Dens.
There they turned to the right and kept on two hundred yards until
they reached the walk coming down from the Reptile House. There
they turned to the left, crossed the bridge, stopped at the gate
to the Wild-Fowl Pond enclosure, and when the gate was opened they
entered and declared themselves "at home."
Mr. Atkin says that in spring these birds show just as much
interest in going back to their summer home. Falconry. We cannot
do otherwise than regard the ancient sport of falconry as a high
tribute to the mental powers of the genus Falco. The
hunting falcons were educated into the sport of hawking, just as a
boy is trained by his big brother to shoot quail on the wing. The
birds were furnished with hoods and jesses, and other garnitures.
They were carried on the hand of the huntsman, and launched at
unlucky herons and bitterns as an intelligent living force.
The hunting falcon entered into the sport like a true sportsman,
and he played the game according to the rules. The sport was
cruel, but it was politely exciting, and it certainly was a fine
exhibition of bird intelligence. Part of that intelligence was
instinctive, but the most of it was acquired, by educational
methods.
Outstanding Traits in a Few Groups of Birds. In creatures as much
lacking in visible expression as most birds are, it is difficult
to detect the emotions and temperaments that prevail in the
various groups. Only a few can be cited with certain confidence.
Vanity Displays in Birds. The males of a few species of birds have
been specially equipped by nature for the display of their natural
vanity. Anyone who has seen a Zoological Park peacock working
overtime on a Sunday afternoon in summer when the crowds of
visitors are greatest, solely to display the ocellated splendor of
his tail plumage, surely must conclude that the bird is well aware
of the glories of his tail, and also that he positively enjoys
showing off to admiring audiences.
These displays are not casual affairs in the ordinary course of
the day's doings. It is a common thing for one of our birds to
choose a particularly conspicuous spot, preferably on an elevated
terrace, from which his display will carry farthest to the eyes of
the crowd. Even if the bird were controlled by the will of a
trainer for the purpose of vanity display, the exhibition could
not possibly be more perfect. Like a good speaker on a rostrum,
the bird faces first in one direction and then in another, and
occasionally with a slow and stately movement it completely
revolves on its axis for the benefit of those in the rear. "Vain
as a peacock" is by no means an unjustifiable comparison.
Plumage displays are indulged in by turkeys, the blue bird of
paradise, the greater and lesser birds of paradise, the sage
grouse and pinnated grouse, ruffed grouse, golden pheasant and
argus pheasant.
On the whole, we may fairly set down vanity as one of the well
defined emotions in certain birds, and probably possessed by the
males in many species which have not been provided by nature with
the means to display it conspicuously.
Materials for Study. In seeking means by which to study the mental
and temperamental traits of wild birds and mammals, the definite
and clearly cut manifestations are so few in kind that we are glad
to seize upon everything available. Of the visible evidences,
pugnacity and the fighting habit are valuable materials, because
they are visible. Much can be learned from the fighting weakness
or strength of animals and men.
In our great collections of birds drawn from all the land areas of
the globe, our bird men see much fighting. Mr. Crandall has
prepared for me in a condensed form an illuminating collection of
facts regarding
PUGNACITY IN CAPTIVE BIRDS
1. Most species do more or less competitive fighting for nesting
sites or mates, especially:
Gallinaceous birds,—many of which fight furiously for mates;
The Ruff, or Fighting Snipe (Machetes pugnax),—very
pugnacious for mates;
House Sparrows (Passer domesticus) fight for nesting places
and mates; and
Some Waterfowl, especially swans and geese, fight for nesting
places.
2. Most species which do not depend chiefly upon concealment,
fight fiercely in defense of nests or young. Typical examples are:
Geese;
Swans;
The larger Flycatchers;
Birds of prey, especially the more powerful ones, such as Bald
Eagles, Duck Hawks and Horned Owls.
3. Some species fight in competition for food. Conspicuous
examples are:
The fiercer hawks;
Some carrion eaters, as the King Vulture, Black, Sharp-Shinned,
Cooper, Gos and Duck Hawks, which fight in the air over prey.
4. Certain birds show pugnacity in connection with the robber
instinct, as:
Bald Eagle, which robs the Osprey;
Skua and Jaeger, which rob gulls.
5. Some species show general pugnacity. Species to be cited are:
Cassowaries, Emus and Ostriches, all of which are more or less
dangerous;
Saras Cranes, which strike wickedly and without warning;
Some Herons, especially if confined, and
Birds of Paradise, which are unreasonably quarrelsome.
6. In non-social birds, each male will fight for his own breeding
and feeding territory. The struggle for territory is a wide one,
and it is now attracting the attention of bird psychologists.
Birds are no more angelic than human beings are. They have their
faults and their mean traits, just as we have; but their
repertoire is not so great as ours. In every species that we have
seen tried out in captivity, the baser passions are present. This
is equally true of mammals. In confinement, in every herd
and in every flock from elephants down to doves, the strong bully
and oppress the weak, and drive them to the wall.
The most philosophic and companionable birds are the
parrots, parakeets, macaws and cockatoos.
The birds that most quickly recognize protection
sanctuaries and accept them, are the geese, ducks and swans.
The game birds most nervous and foolish, and difficult to
maintain in captivity, are the grouse, ptarmigan and quail.
The bird utterly destitute of sense in captivity is the
loon.
The birds that are most domineering in captivity are the
cranes.
The birds that are most treacherous in captivity are the
darters (Anhinga).
The birds that go easiest and farthest in training are the
parrots, macaws and cockatoos.
The most beautiful bird species of the world are about
fifty in number; and only a few of them are found among the birds
of paradise.
The minds of wild birds are quite as varied and diversified as are
the forms and habits of the different orders and genera. XVI
THE WISDOM OF THE SERPENT
OF all the vertebrates, the serpents live under the greatest
handicaps. They are hated and destroyed by all men, they can
neither run nor fly far away, and they subsist under maximum
difficulties. Those of the temperate zone are ill fitted to
withstand the rigors of winter.
And yet the serpents survive; and we have not heard of any species
having become extinct during our own times.
It is indeed worth while to "consider the wisdom of the serpent."
Without the exercise of keen intelligence all the snakes of the
cultivated lands of the world long ago would have been
exterminated. The success of serpents of all species in meeting
new conditions and maintaining their existence in the face of
enormous difficulties compels us, as reasoning beings, to accord
to them keen intelligence and ratiocination.
The poisonous serpents afford a striking illustration of reason
and folly en masse. The total number of venomous species is really
great, and their distribution embraces practically the whole of
the torrid and temperate zones. They are too numerous for mention
here; and their capacity for mischief to man is very great. Our
own country has at least eighteen species of poisonous snakes,
including the rattlesnakes, the copperhead, moccasin, and coral
snakes. All these, however, are remarkably pacific. Without
exception they are non-aggressive, and they attack only when they
think they are exposed to danger, and must defend themselves or
die. Hundreds of thousands, or even millions, of our people have
tramped through the woods and slept in the sage-brush and creosote
bushes of the rattlesnake, and waded through swamps full of
moccasins, with never a bite. In America only about two persons
per year are bitten by wild rattlesnakes.
Our snakes, and all but a very few of the other poison-snake
species of the world, know that it pays to keep the peace.
Now, what if all snakes were as foolishly aggressive as the hooded
and spectacled cobras of India? Let us see.
Those cobra species are man-haters. They love to attack and do
damage. They go out of their way to bite people. They crawl into
huts and bungalows, especially during the monsoon rains, and they
infest thatch roofs. But are they wise, and retiring, like the
house-haunting gopher snake of the South?
By no means. The cobra goes around with a chip on his shoulder. In
India they kill from 17,000 to 18,000 people annually! And in
return, about 117,000 cobras are killed annually. It is a mighty
fortunate thing for humanity on the frontier that the other
serpents of the world know that it is a good thing to behave
themselves, and not bite unnecessarily.
Fighting Its Own Kind. The Indian cobra, (Naia tripudians),
is an exception to the rule of serpents that forbids fighting in
the family. While cobras in captivity usually do live together in
a state of vicious and fully-armed neutrality, sometimes they do
fight. One of our cobras once attacked a cage-mate two-thirds the
size of itself, vanquished it, seized it by the head and swallowed
two-thirds of it before the tragedy was discovered. The assailant
was compelled to disgorge his prey, but the victim was very dead.
The poison venom of the cobra, rattlesnake, bushmaster and puff
adder is a great handicap on the social standing of the entire
serpent family. Mankind in general abhors snakes, both in general
and particular. The snake not actually known to be venomous
usually is suspected of being so. It is only the strongest mental
constitution that can permit a snake to go unkilled when the
killing opportunity offers. It is just as natural for the lay
brother to kill a chicken snake because it looks like a
copperhead, or a hog-nosed blowing "viper" because it looks like a
rattlesnake, as it is to shy at a gun that "may be loaded."
To American plainsmen, the non-aggressive temper of the
rattlesnake is well known, and it is also a positive asset. I
never knew one who was nervously afraid while sleeping in the open
that snakes would come and crawl into his bed, or mix up with his
camp. Of course all frontiersmen kill rattlers, as a sort of
bounden duty to society, but I once knew an eastern man to turn
loose a rattlesnake that he had photographed, in the observance
of his principle never to kill an animal whose picture he had
taken. Subsequently it was gravely reported that one of the
restive horses of the outfit had "accidentally" killed that
rattler by stepping upon it.
A Summary of Poisonous Snakes. There are about 300,000 poisonous
snakes in the United States, and 110,000,000 people for them to
bite; but more people are bitten by captive snakes than by wild
ones.
A fool and his snake are soon parted.
There are 200,000 rattlesnakes in our country, but all of them
will let you alone if you will let them alone.
If your police record is clear, you can sleep safely in the sage-
brush.
If ever you need to camp in a cave, remember that in warm weather
the rattlesnakes are all out hunting, and will not return until
the approach of winter.
The largest snakes of the world exist only in the human mind.
The rattlesnake is a world-beater at minding his own business.
Men do far more fighting per capita than any snakes yet
discovered.
The road to an understanding of the minds of serpents is long and
difficult. Perhaps the best initial line of approach is through a
well-stocked Reptile House. Having studied somewhat
in that school I have emerged with a fixed belief that of all
vertebrate creatures, snakes are the least understood, and also
the most thoroughly misunderstood.
[Illustration: A
PEACE CONFERENCE WITH AN ARIZONA RATTLESNAKE "You let me alone and
I won't harm you" (From "Camp-Fires on Desert and Lava")]
[Illustration: HAWK-PROOF NEST OF A CACTUS WREN Placed in the
centre of a tree choya cactus of Arizona and defended by 10 000
hostile spines (From "Camp-Fires on Desert and Lava")]
The world at large debits serpents with being far more quarrelsome
and aggressive than they really are, and it credits them with
knowing far less than they do know.
Attitude of Snakes Toward Each Other. Toward each other, the
members of the various serpent species are tolerant, patient and
peaceful to the last degree. You may place together in one cage
twenty big Texas rattlers, or twenty ugly cottonmouth moccasins
from the Carolinas, a hundred garter snakes, twenty boa
constrictors, or six big pythons, and if the various
species are kept separate there will be no fighting. You
may stir them up to any reasonable extent, and make them keen to
strike you, but they do not attack each other.
There are, however, many species that will not mix together in
peace. For example, the king snake of New Jersey hates the
rattlesnake, no matter what his address may be. Being by habit a
constrictor, the king snake at once winds himself tightly around
the neck of the rattler,—and proceeds to choke him to death.
The king cobra devours other snakes, as food, and wishes nothing
else.
The Gopher Snake. Some snakes that feel sure you will not harm
them will permit you to handle them without a protest or a fight.
The most spectacular example is the gopher snake of the
southeastern United States. This handsome, lustrous, blue-black
species is six feet long, shiny, and as clean and smooth as ivory.
Its members are famous rat-killers. You can pick up a wild one
wherever you find it, and it will not bite you. They do not at all
object to being handled, even by timorous lady visitors who never
before have touched a live snake; and in the South they are
tolerated by farmers for the good they do as rat catchers.
The Wisdom of a Big Python. Once I witnessed an example of snake
intelligence on a large scale, which profoundly impressed me.
A reticulated python about twenty-two feet long arrived from
Singapore with its old skin dried down upon its body. The snake
had been many weeks without a bath, and it had been utterly unable
to shed its old skin on schedule time. It was necessary to remove
all that dead epidermis, without delay.
The great serpent, fully coiled, was taken out of its box, sprayed
with warm water, and gently deposited on the gravel floor of our
most spacious python apartment. Later on pails of warm water,
sponges and forceps were procured, and five strong keepers were
assembled for active service.
The first step was to get the snake safely into the hands of the
men, and fully under control. A stream of cold water from a hose
was suddenly shot in a deluge upon the python's head, and while it
was disconcerted and blinded by the flood, it was seized by the
neck, close behind the head. Immediately the waiting keepers
seized it by the body, from neck to tail, and straightened it out,
to prevent coiling. Strong hands subdued its struggles, and
without any violence stretched the writhing wild monster upon the
floor.
Then began the sponging and peeling process. The frightened snake
writhed and resisted, probably feeling sure that its last hour had
come. The men worked quietly, spoke soothingly, and the work
proceeded successfully. With the lapse of time the serpent became
aware of the fact that it was not to be harmed; for it became
quiet, and lay still. At the same time, we all dreaded the crisis
that we thought would come when the jaws and the head would be
reached.
By the time the head was reached, the snake lay perfectly passive.
Beyond all doubt, it understood the game that was being played.
Now, the epidermis of a snake covers the entire head, including
the eyes! And what would that snake do when the time came to
remove the scales from its eyes and lips? It continued to lie
perfectly still! When the pulling off of the old skin hurt the new
skin underneath, the head flinched slightly, just as any hurt
flesh will flinch by reflex action; but that was absolutely all.
For a long hour or more, and even when the men pulled the dead
scales from those eyes and lips, that strange creature made no
resistance or protest. I have seen many people fight their doctors
for less.
That wild, newly-caught jungle snake quickly had recognized the
situation, and acted its part with a degree of sense and
appreciation that was astounding. I do not know of any adult
wild mammal that would have shown that kind and degree of
wisdom under similar circumstances.
Do Snakes "Charm" Birds? Sometimes a wild bird will sit still upon
its nest while a big pilot blacksnake, or some other serpent
equally bad, climbs up and poises its head before the motionless
and terrified bird until at last the serpent seizes the bird to
devour it. The bird victim really seems to be "charmed" by its
enemy. If there were not some kind of a hypnotic spell cast over
the bird, would it not fly away?
I think this strange proceeding is easily explainable by any one
with sufficient imagination to put himself in the bird's place. It
is the rule of a sitting bird to sit tight, not to be scared off
by trifles, and to take great risks rather than expose her eggs to
cold and destruction. The ascent and approach of the serpent is
absolutely noiseless. Not a leaf is stirred. The potential mother
of a brood calmly sits with eyes half closed, at peace with all
the world. Suddenly, and with a horrible shock, she discovers a
deadly serpent's multi-fanged head and glittering eyes staring at
her within easy striking distance.
The horrified mother bird feels that she is lost. She knows full
well that with any movement to escape the serpent instantly will
launch its attack. Her one hope, and seemingly her only
chance for life, is that if she remains motionless the
serpent will go its way without harming her. (Think of the
thousands of helpless men, women and children who have hoped and
acted similarly in the presence of bandits and hold-up men
presenting loaded revolvers! But they were far from being
"charmed.")
The bird hopes, and sits still, paralyzed with fear. At its
leisure the serpent strikes; and after a certain number of
horrible minutes, all is over. I think there is no real "charm"
exercised in the tragedy; but that there is on the part of the
bird a paralysis of fear, which is in my opinion a well defined
emotion, common in animals and in men. I have seen it in many
animals.
Snakes that Feign Death. The common hog-nosed snake, mistakenly
called the "puff-adder" and blowing "viper" (Heterodon
platyrhinus) of the New England states, often feigns death
when it is caught in the open, and picked up. It will "play
'possum" while you carry it by its tail, head downward, or hang
its limp body over a fence. Of course it hopes to escape by its
very clever ruse, and no doubt it often does so from the hands of
inexperienced persons.
Do Snakes Swallow Their Young? I think not. A number of
persons solemnly have declared that they have seen snakes do so,
but no herpetologist ever has seen an occurrence of that
kind. I believe that all of the best authorities on serpents
believe that snakes do not swallow their young. The theory of the
pro-swallowists is that the mother snake takes her young into her
interior to provide for their safety, and that they do not go as
far down as the stomach. The anti-swallowists declare that the
powerful digestive juices of the stomach of a snake would quickly
kill any snakelets coming in contact with it; and I believe that
this is true.
At present the snake-swallowing theory must be ticketed "not
proven," and is filed for further reference.
The Hoop Snake Fable. There is no such thing as a "hoop-snake"
save in the vivid imaginations of a very few men.
The Intelligence of the King Cobra. Curator of Reptiles Raymond
L. Ditmars regards the huge king cobra of the Malay Peninsula, the
largest of all poisonous serpents, as quite the wisest serpent
known to him. He says its mind is alert and responsive to a very
unusual degree in serpents, and that it manifests a keen interest
in everything that is going on around it, especially at feeding-
time. This is quite the reverse of the usual sluggish and
apathetic serpent mind in captivity.
Incidentally, I would like very much to know just what our present
twelve-foot cobra thought when, upon its arrival at its present
home, its total blindness was relieved by the thrillingly skilful
removal of the two layers of dead scales that had closed
over and finally adhered to each orbit.
The vision of the king cobra is keen, and its temper is not easily
ruffled. Its temperament seems to be sanguine, which is just the
opposite of the nervous-combative hooded and spectacled cobra
species.
The So-called "Snake Charmers" of India. Herpetologists generally
discredit the idea that a peripatetic Hindu can "charm" a cobra
any farther or more quickly than any snake-keeper. In the first
place, the fangs of the serpent are totally removed,—by a very
savage and painful process. After that, the unfortunate snake is
in no condition to fight or to flee. It seeks only to be let
alone, and the musical-pipe business is to impress the mind of the
observer.
Serpent Psychology an Unplowed Field. At this date (1922) we know
only the rudiments of serpent intelligence and temperament. In the
wilds, serpents are most elusive and difficult to determine. In
captivity they are passive and undemonstrative. We do not know how
much memory they have, they rarely show what they think, and on
most subjects we do not know where they stand. But the future will
change all this. During the past twenty years the number of
herpetologists in the United States has increased about tenfold.
It is fairly impossible that serpent psychology should much longer
remain unstudied, and unrevealed along the lines of plain common-
sense.
The Ways of Crocodiles. The ways of crocodiles are dark and deep;
their thoughts are few and far between. Their wisdom is above that
of the tortoises and turtles, but below that of the serpents. I
have had field experience with four species of crocodilians in the
New World and three in the Old. With but slight exceptions they
all think alike and act alike.
The great salt-water crocodile of the Malay Peninsula and Borneo
is the only real man-eater I ever met. Except under the most
provocative circumstances, all the others I have met are
practically harmless to man. This includes the Florida species,
the Orinoco crocodile, the little one from Cuba, the alligator,
the Indian gavial and the Indian crocodile (C. palustris).
The salt-water crocodile, that I have seen swimming out in the
ocean two miles or more from shore, is in Borneo a voracious man-
eater. It skilfully stalks its prey in the murky rivers where
Malay and Dyak women and children come down to the village bathing
place to dip up water and to bathe. There, unseen in the muddy
water, the monster glides up stealthily, seizes his victim by the
leg, and holding it tightly backs off into deep water and
disappears. The victims are drowned, not bitten to death.
I found in Ceylon that the Indian crocodile is a shameless
cannibal, devouring the skinned carcasses of its relatives
whenever an opportunity offered.
The Florida crocodile is the shrewdest species of all those I know
personally. It has the strange habit of digging out deep and
spacious burrows for concealment, in the perpendicular sandy
banks of southern Florida rivers where the deep water comes right
up to the shore. Starting well under low-water mark, the crock
digs in the yielding sand, straight into the bank, a roomy
subterranean chamber. In this snug retreat he once was safe from
all his enemies,—until the fatal day when his secret was
discovered, and revealed to a grasping world. Since that time, the
Alligator Joes of Palm Beach and Miami have made a business of
personally conducting parties of northern visitors, at $50 per
catch, to witness the adventure of catching a nine-foot crocodile
alive. The dens are located by probing the sand with long iron
rods. A rope noose is set over the den's entrance, and when all is
ready, a confederate probes the crocodile out of its den and into
the fatal noose.
Today the Florida crocodile is so nearly extinct that it required
two years of diligent inquiry to produce one live specimen subject
to purchase.
Common Sense in the Common Toad. Last spring, in planting a lot of
trees on our lawn, a round tree-hole that stood for several days
unoccupied finally accumulated about a dozen toads. Its two feet
of straight depth was unscalable, and when finally discovered the
toads were tired of their imprisonment. Partly as a test of their
common-sense, Mr. George T. Fielding placed a six-inch board in
the hole, at an angle of about thirty degrees, but fairly leading
out of the trap.
In very quick time the toads recognized the possibilities of the
inclined plane and hopped upward to liberty. In the use of this
opportunity they showed more wisdom than our mountain sheep
manifest concerning the same kind of an improvement designed to
enable them to reach the roof of their building. XVII
THE TRAINING OF WILD ANIMALS
Before we enter this chapter let us pause a moment on the
threshold, and consider the logic of animal training and
performances.
Logic is only another name for reason. Its reverse side is
fanaticism; and that way madness lies. It is the duty of every
sane man and woman to consider the cold logic of every question
affecting the welfare of man and nature. Fanaticism when carried
to extremes can become a misdemeanor or a crime. The soft-hearted
fanaticism of humanics that saves a brutal murderer, or would-be
murderer like Berkman, from the gallows or the chair, and
eventually turns him loose to commit more crimes against innocent
people, is not only wrong, and wicked, but in aggravated cases it
is a crime against society.
Just now there is a tiny wave of agitation against all
performances of trained wild animals, and the keeping of animals
in captivity, on the ground that all this is "cruel" and inhumane.
The Jacklondon Society of Boston is working hard to get up steam
for this crusade, but thus far with only partial success. Its
influence is confined to a very small area.
Now, what is the truth of this matter? Is it true that trained
wild animals are cruelly abused in the training, or in compelling
them to perform? Is it true that in making animals perform on the
stage, or in the circus ring, their rights are wickedly infringed?
Is it the duty of the American people to stop all performances by
animals? Is it wicked to make wild animals, or cats and dogs,
work for a living, as men and women do? Is it true that
captive animals in zoological parks and gardens are miserable and
unhappy, and that all such institutions should be "abolished?"
What is truth?
In the first place, there is no sound reasoning or logic in
assuming that the persons of animals, tame or wild, are any more
sacred than those of men, women and children. We hold that it is
no more "cruelty" for an ape or a dog to work in training quarters
or on the stage than it is for men, women and young people to work
as acrobats, or actors, or to engage in honest toil eight hours
per day. Who gave to any warm-blooded animal that consumes food
and requires shelter the right to live without work? No
one! I am sure that no trained bear of my acquaintance ever
had to work as hard for his food and shelter as does the average
bear out in the wilds. In order to find enough to eat the latter
is compelled to hustle hard from dawn till dark. I have seen that
the Rocky Mountain grizzly feels forced to dig a big hole three
feet deep in hard, rocky ground, to get one tiny ground squirrel
the size of a chipmunk,—and weighing only eight or nine ounces.
Now, has he anything "on" the performing bear? Decidedly not.
I regard the sentimental Jacklondon idea, that no wild animal
should be made to work on the stage or in the show-ring, as
illogical and absurd. Human beings who sanely work are much
happier per capita than those who do nothing but loaf and grouch.
I have worked, horse-hard, throughout all the adult years of my
life; and it has been good for me. I know that it is no more wrong
or wicked for a horse to work for his living,—of course on a
humane basis,—either on the stage or on the street, than it is
for a coal-carrier, a foundryman, a farmer, a bookkeeper, a school
teacher or a housewife to do the day's work.
The person of a wild animal is no more sacred than is that of a
man or woman. A sound whack for an unruly elephant, bear or horse
is just as helpful as it is for an unruly boy who needs to be
shown that order is heaven's first law.
In the presence of the world's toiling and sweating millions, in
the presence of millions of children in the home sweat-shops and
factories working their little lives out for their daily crust and
a hard bed, what shall we think and say of the good, kind-hearted
people who are spending time and energy in crusading against
trained animal performances?
The vast majority of performing animals are trained by humane men
and women, practicing kindness to the utmost; and they are the
last persons in the world who would be willing to have their
valuable stock roughly handled, neglected or in any manner cruelly
treated.
So far as zoological parks and gardens are concerned, they are no
more in need of defense than the Rocky Mountains.
Every large zoological park is a school of wild-animal education
and training; and it is literally a continuous performance. Let
no one suppose that there is no training of wild beasts save for
the circus ring and the vaudeville stage. Of the total number of
large and important mammals that come into our zoological parks,
the majority of them actually are trained to play becomingly their
respective parts. An intractable and obstinate animal soon becomes
a nuisance.
The following, named in the order of their importance, are the
species whose zoological park training is a matter of necessity:
Elephants, bears, apes, hippopotami, rhinoceroses, giraffes,
bison, musk-ox, wild sheep, goats and deer, African antelopes,
wild swine, and wild horses, asses and zebras. Of large birds the
most conspicuous candidates for training in park life are the
ostriches, emus, cassowaries, cranes, pelicans, swans, egrets and
herons, geese, ducks, pheasants, macaws and cockatoos, curassows,
eagles and vultures. Among the reptiles, the best trained are the
giant tortoises, the pythons, boas, alligators, crocodiles,
iguanas and gopher snakes.
Each one of these species is educated (1) to be peaceful, and not
attack their keepers; (2) to not fear their keepers; (3) to do as
they are bid about going here or there; (4) to accept and eat the
food that is provided for them, and (5) finally, in some cases to
"show off" a little when commanded, for the benefit of visitors.
All this training comes in the regular course of our daily work,
and there are few animals who do not respond to it. The necessity
for training is most imperative with the elephants and bears, for
without it the difficulties in the management of those dangerous
animals is greatly intensified.
In training an animal to do a particular act not in the routine of
his daily life, it is of course necessary to show him clearly and
pointedly what is desired. I think that in quickness of
perception, and ability to adopt a new idea, the elephants and
the great apes are tied for first place. Both are remarkably
quick. It seems to me that it required only half a dozen lessons
to teach our Indian elephant, Gunda, to take a penny in his trunk,
lift the lid of a high-placed box, drop in the coin, then pull a
bell-cord and ring a bell. Of course the reward for the first
successful performances was lumps of sugar. Within three days this
rather interesting special exhibit was working smoothly, and
coining money. As a means of working off on the poor animal great
numbers of foreign copper coins, and spurious issues of all kinds,
it was a great boon to the foreign population of New York. Our
erratic elephant Alice was quickly trained by Keeper Richards to
blow a mouth organ, to ring a telephone by turning the crank, and
to take off the receiver and hold it up to her ear for an
imaginary call.
Another keeper, with no previous experience as a trainer, taught a
male orang-utan called Rajah to go through a series of
performances that are elsewhere described.
Bright and Dull Individuals. Every wild animal species contains
the same range of bright and dull individuals that are found in
the various races of men. Naturally the animal trainer selects for
training only those animals that are of amiable disposition, that
mentally are alert, responsive and possessed of good memories. The
worst mistakes they make are in taking on and forcing ill-natured
and irritable animals, that hate training and performing. Often a
trainer persists in retaining an animal that resolutely should be
thrown out. Captain Bonavita lost his arm solely because of his
fatal persistence in retaining in his group of lions an animal
that hated him, and which the trainer well knew was dangerous.
While nearly every wild animal can be taught a few simple tricks,
the dull mind soon reaches its constitutional limit. Even among
the great apes, conditions are quite the same. One half the orang-
utans are of the thin-headed, pin-headed type that is hopeless for
stage training. The good ones are the stocky, round-headed, round-
faced individuals who have the cephalic index of the statesman or
jurist, and a broad and well-rounded dome of thought.
Training for the Ring and the Stage. During his long and
successful career as a purveyor of wild animals for all purposes,
Carl Hagenbeck had great success in the production of large
animal groups trained for stage performances. I came in close
touch with his methods and their results. His methods were very
simple, and they were founded on kindness and common sense. Mr.
Hagenbeck hated whips and punishments. When an animal could not
get on without them, it was dropped from the cast. His working
theory was that an unwilling animal makes a bad actor.
There is no mystery about the best methods in training animals,
wild or domestic. The first thing is to assemble a suitable number
of young animals, all of which are mentally bright and
physically sound. Most adult animals are impracticable, and often
impossible, because they are set in their ways. The elephants are
monumental exceptions. A large, well-lighted and sunny room is
provided; and around it are the individual cages for the student
animals. The members of the company are fed wisely and well, kept
scrupulously clean, and in all ways made comfortable and
contented. When not at their work they are allowed to romp and
play together until they are tired of the exercise.
The trainer who has been selected to create a specified group
spends practically his entire time with his pupils. He feeds them,
and mixes with them daily and hourly. From the beginning he
teaches them that they must obey him, and not fight.
The work of training begins with simple things, and goes on
to the complex; and each day the same routine is carried out.
To each animal is assigned a certain place in the circle, with
a certain tub or platform on which to sit at ease when not
acting in the ring. It is exceedingly droll to see a dozen cub
lions, tigers, bears and cheetahs sitting decorously on their
respective tubs and gravely watching the thirteenth cub who
is being labored with by the keeper to bring its ideas and acts
into line. The stage properties are many; and they all assist in
helping the actors to remember the sequence of their acts, as well
as the things to be done. The key that controls the mind of a good
animal is the reward idea. Many a really bad animal goes through
its share of the performance solely to secure the bit of meat, the
lump of sugar or the prized biscuit that never fails to show up at
the proper moment.

(From A. G. R. Theobald, Mysore)]
The acts to be performed are gone over in the training quarters,
innumerable times; and this continues so long that by the time the
"group" is ready for the stage, behold! the cubs with which the
patient and tireless trainer began have grown so large that to the
audience they now seem like adult and savage animals. Those who
scoff at the wild animal mind, and say that all this displays
nothing but "machines in fur" need to be reminded that this very
same line of effort in training and rehearsal is absolutely
necessary in the production of every military company, every
ballet, and every mass performance on the stage. There is
no successful performance without training. Boys and girls
require the very same sort of handling that the wild animals
receive, but the humans do with a little less of it.
The man who flouts a good stage performance by wild animals on the
ground that it reveals "no thought," and is only "imitation," is,
in my judgment, a very short-sighted student. Maniacs and
imbeciles cannot be trained to perform any program fit to be seen.
I saw that tried fifty years ago, in "the wild Australian
children," who were idiots. The performer must think, and
reason.
Of the many groups of trained animals that I have seen in
performances, my mind goes back first to the one which contained
a genuine bear comedian, of the Charlie Chaplin type. It was a
Himalayan black bear, with fine side whiskers, and it really
seemed to me absolutely certain that the other animals in the
group appreciated and enjoyed the fun that comedian made. He
pretended to be awkward, and frequently fell off his tub. He was
purposely dilatory, and was often the last one to finish. The
other animals seemed to be fascinated by his mishaps, and they sat
on their tubs and watched him with what looked like genuine
amusement. I remember another circle of seated animals who calmly
and patiently sat and watched while the trainer labored with a
cross and refractory leopard, to overcome its stubbornness, and to
make it do its part.
Carl Hagenbeck loved to produce mixed groups of dangerous
animals,—lions, tigers, leopards, bears and wolves. One trainer
whom I knew was assisted in a highly dangerous group by a noble
stag-hound who habitually kept close to his master, and was said
to be ready to attack instantly any animal that might attack the
trainer. I never saw a finer bodyguard than that dog.
In 1908 the most astounding animal group ever turned out of the
Hagenbeck establishment, or shown on any stage, appeared in
London. It consisted of 75 full-grown polar bears! Now,
polar bears, either for the cage or the stage, are bad citizens.
Instinctively I always suspect their mental reservations, and for
twenty-one years have carefully kept our keepers out of their
reach. But Mr. William Hagenbeck, brother of the great Carl,
actually trained and performed with a huge herd of
dangerous polars to the number stated.
In the Strand magazine for April, 1908, there is a fine
article by Arthur Harold about this group and its production. It
says that the bears were obtained when seven or eight months old,
in large lots, and all thrown in together. It took a keeper
between seven and eight months to educate them out of their savage
state,—by contact, kindness, sugar and fruit,—and then they were
turned over to the trainer, Mr. Hagenbeck. They were taught to
form pyramids, climb ladders, shoot the chutes, ride in pony
carriages, draw and ride in sleds, drink from bottles, and work a
see-saw. Various individuals did individual tricks. The star
performer was Monk, the wrestling bear, who went with his trainer
through a fearsome wrestling performance.
Concerning the temperament of that polar bear group Mr. William
Hagenbeck said:
"Although I know every animal in the company, have taught each one
to recognize me, and have been among many of them for fifteen
years, I can not now tell by their expressions the moods of
the animals. This is one of the characteristics of the polar bear.
Their expression remains the same, and it is impossible to detect
by watching their faces whether they are pleased or cross. Now in
most wild animals, such as the lion, you can tell by the
expression of the beast's face and by its actions whether it is in
a good temper or not…. The truth is, the polar bear is a most
awkward beast to train. In the first place its character is
difficult to understand. He is by nature very suspicious, and
without the least warning is apt to turn upon his trainer. Among
the seventy bears that have been taught to do tricks, only
two of them are really fond of their work."
In the end, Mr. William Hagenbeck was very nearly killed by one of
these polar bears. I was with Carl Hagenbeck a few hours after he
received telegraphic news of the tragedy, and his bitterness
against those polar bears was boundless. I understood that Monk,
the wrestling bear, was the assailant,—which was small cause for
wonder. When I saw Mr. Hagenbeck's polar bear show, it gave me
shivers of fear. The first two big male polars that we installed
at our Park came from that very group, and one of them led us into
a dreadful tragedy, with a female bear as the victim.
The So-Called "Trick" Performances. Some psychologists make light
of what they call "trick performances," in which the performing
animals are guided by signs, or signals, or spoken commands from
their trainers. I have never been able to account for this. It is
incontestably true that dull and stupid animals can learn little,
and perform less. For example, all the training in the world could
not suffice to put a pig through a performance that a chimpanzee
or orang could master in two weeks. The reason is that the pig has
not the brain power that is indispensable. A woodchuck never could
become the mental equal of a wood rat (Neotoma). A sheep
could not hope to rival a horse, either in training or in
execution.
Really, the brain, the memory and reason must enter into every
animal performance that amounts to anything worth while. It is
just as sensible to flout soldiers on the drill-ground as to wave
aside as of no account a troup of trained lions or sea-lions on
the stage. Any animal that can be taught to perform difficult
feats, and that delivers the goods in the blinding glare and riot
of the circus ring or the stage footlights, is entitled to my
profound respect for its powers of mind and nerve.
The Sea-Lion's Repertoire. Long ago trainers recognized in the
California sea-lion (Zalophus) a good subject for the ring
and stage. Its long, supple neck, its lithe body and brilliant
nervous energy seemed good for difficult acts. The sea-lion takes
very kindly to training, and really delights in its performances.
In fact, it enters into its performance with a keen vigor and zest
that is pleasing to behold. Let this veracious record of a
performance of Treat's five sea-lions and two harbor seals, that I
witnessed October 15, 1910, tell the whole story, in order that
the reader may judge for himself:
1. Each sea-lion balanced upright on its nose a wooden staff 3
feet long, with a round knob on its upper end.
2. Each sea-lion caught in its mouth a three-foot stick with a
ball on each end, tossed it up, whirled it in the air, and caught
it again. This was repeated, without a miss.
3. Each sea-lion balanced on the tip of its nose, first a ball
like a baseball, then a large ball two feet in diameter.
4. Each sea-lion climbed a double ladder of eight steps, and went
down on the other side, balancing a large ball on the end of
its nose, without a miss.
5. The trainer handed a ball to the sea-lion nearest him, who
balanced it on his nose, walked with it to his box and climbed up.
6. Then another sea-lion walked over to him, and waited
expectantly until sea-lion No. 1 tossed the ball to No. 2, who
caught it on his nose, walked over to his box, climbed up, and
presently tossed it to No. 3.
7. A silk hat was balanced on its rim.
8. A seal carrying a balanced ball scrambled upon a cylindrical
basket and rolled it across the arena, after which other seals
repeated the performance.
9. In the last act a flaming torch was balanced, tossed about,
caught and whirled, and finally returned to the trainer, still
blazing.
Trained Horses. By carefully selecting the brightest and most
intelligent horses that can be found, it is possible for a trainer
to bring together and educate a group that will go through a fine
performance in public. However, some exhibitions of trained
horses are halting, ragged and poor. I have seen only one that
stands out in my records as superlatively fine,—for horses. That
was known to the public when I saw it as Bartholomew's "Equine
Paradox," and it contained twelve wonderfully trained horses. My
record of this fine performance fills seven pages of a good-sized
notebook. While it is too long to reproduce here entire, it can at
least be briefly described. The trainer called his group a
"school," and of it he said:
"While I do not say that any one horse knows the meaning of from
300 to 400 words, I claim that as a whole the school does
know that number."
The performance was fairly bewildering; but by diligent work I
recorded the whole of it. Various horses did various things. They
fetched chairs, papers, hats and coats; opened desks, rang bells,
came when called, bowed, knelt, and erased figures from a
blackboard. They danced a waltz, a clog dance, a figure-8; they
marched, halted, paced, trotted, galloped, backed, jumped, leaped
over each other, performed with a barrel, a see-saw and a double
see-saw. Their marching and drilling would have been creditable to
a platoon of rookies.
In performing, every horse is handicapped by his lack of hands and
plant grade feet; and the horse memory is not very sure or
certain. More than any other animal, the horse depends upon the
trainer's command, and in poor performances the command often
requires to be repeated, two or three times, or more. The memory
of the horse is not nearly so quick nor so certain as that of the
chimpanzee or elephant.
Dr. Martin J. Potter, of New York, famous trainer of stage and
movie animals, states that of all animals, wild or domestic, the
horse is the most intelligent; but I doubt whether he ever trained
any chimpanzees. Speaking from out of the abundance of his
training experience with many species of animals except the great
apes, Dr. Potter says that "the seal [i. e. California sea-lion]
learns its stage cues more easily than any other mute performer.
The horse, however, is the most intelligent of all animals in its
grasp and understanding of the work it has learned to perform, and
in its reliable faithfulness and memory." Dr. Potter holds that
of wild animals the tiger, owing to its treachery and ferocity, is
the most difficult wild animal to train; the lion is the most
reliable, and the most stupid of all animals is the pig.
The Taming of Boma. A keeper for a short time in our place, named
D'Osta, once did a very neat piece of work in taming a savage and
intractable chimpanzee. When Boma came to us, fresh from the
French Congo, he was savage and afraid. He retreated to the
highest resting-place of his cage, came down only at night for his
meals, and would make no compromise. We believed that he had been
fearfully abused by his former owners, and through mistreatment
had acquired both fear and hatred of all men.
After the lapse of several months with Boma on that basis, the
situation grew tiresome and intolerable. So D'Osta said:
"I must tame that animal, and teach him not to be afraid of us."
He introduced a roomy shifting cage into Boma's compartment,
fixed the drop door, and for many days served Boma's food and
water in that cage only. For two weeks the ape eluded capture, but
eventually the keeper caught him. At first Boma's rage and fear
were boundless; but presently the idea dawned upon his mind that
he was not to be killed immediately. D'Osta handed him excellent
food and water, twice a day, spoke to him soothingly, and
otherwise let him alone. Slowly Boma's manner changed. He learned
that he was not to be hurt, nor even annoyed. Confidence in the
men about him began to come to him. His first signs of
friendliness were promptly met and cultivated.
At the end of ten days, D'Osta opened the sliding door, and Boma
walked out, a wiser and better ape. His bad temper and his fears
were gone. He trusted his keeper, and cheerfully obeyed him.
Strangest of all, he even suffered D'Osta to put a collar upon
him, and chain him to the front bars to curb his too great
playfulness while his cage was being cleaned.
Boma's fear of man has never returned. Now, although he is big and
dangerous, he is a perfectly normal ape.
The Training of an Over-Age Bear. A bear-trainer-athlete and
"bear-wrestler" named Jacob Glass once taught me a lesson that
astounded me. It related to the training of a bear that I thought
was too old to be trained.
We had an Alaskan cinnamon bear, three years old, that had been
christened "Christian," at Skagway, because it stood so much
pestering without flying into rages, as the grizzly did. After a
short time with us, the concrete floors of our bear dens reacted
upon the soles of its feet so strangely and so seriously that we
were forced to transfer the animal to a temporary cage that had a
wooden floor. While I was wondering what to do with that bear,
along came Mr. Glass, anxious and unhappy.
"My wrestling bear has died on me," he said, "and I've got to get
another. You have got one that I would like to buy from you. It's
the one you call Christian."
Very kindly I said, "That is a mighty fine bear, as to temper; but
now he is entirely too old to train, and you couldn't do anything
with him. He would be a loss to you."
"I've looked him over, and I like his looks. I think I can train
him all right. You let me have him, and I'll make a fine performer
of him."
"I know that you never can do it; but you may try him, and send
him back when you fail."
Thus ended the first lesson; and I was sure that in a month Mr.
Glass would beg me to take back the untrainable animal.
About one year later Glass appeared again, jubilant. At once he
broke forth into eulogies of Christian; but one chapter would not
be large enough to contain them. He had trained that bear, with
outrageous ease and celerity, and hadimmediately taken him upon
the stage as a professional jiu-jitsu wrestler. And really, the
act was admirable. As a wrestler, the bear seemed almost as
intelligent as the man. He knew the "left-hand half-nelson" as well
as Glass, and he knew the following words, perfectly: "Right,
left, half-nelson, strangle, head up, nose under arm, and
hammer-lock."
[Illustration with caption: THE WRESTLING BEAR "CHRISTIAN" AND HIS
PARTNER]
Glass declared that this bear was more intelligent than any lion,
or any other trained animal ever seen by him. He was wise in many
ways besides wrestling,—in his friendship with Glass, with other
bears, with other men, and with a dog. He obeyed all orders
willingly, even permitting Glass to take his food away when he
was eating; but he would not stand being punished with a whip or
a stick! In response to that he would bite. However, he generously
permitted himself to be held down and choked, as a
punishment, after which he would be very repentant, and would
insist upon getting into his partner's lap,—to show his good
will.
Glass was enthusiastically certain that Christian could reason
independently from cause to effect. He declared that his alertness
of mind was so pronounced it was very rarely necessary to show him
a second time how to do a given thing.
Training an Adult Savage Monkey. Once we had a number of Japanese
red-faced monkeys, and one of the surplus adult males had a temper
as red as his face. Mr. Wormwood, an exhibitor of performing
monkeys, wished to buy that animal; but I declined to sell it, on
the ground that it would be impossible to train it.
At that implied challenge the trainer perked up and insisted upon
having that particular bad animal; so we yielded. He wished him
for the special business of turning somersaults, because he had no
tail to interfere with that performance.
Two months later Mr. Wormwood appeared again. "Yes," he said, but
not boastfully, "I trained him; but I came mighty near to
giving him up as a bad job. He was the hardest subject I ever
tackled; but I conquered him at last, and now he is working all
right."
A really great number of different kinds of animals have been
trained for stage performances, running the scale all the way up
from fleas to elephants. It is easy to recall mice, rats, rabbits,
squirrels, parrots, macaws, cockatoos, crows, chickens, geese,
cats, pigs, dogs, monkeys, baboons, apes, bears, seals, sea-lions,
walruses, kangaroos, horses, hippopotami and elephants. It is a
large subject, and its many details are full of interest. It is
impossible to discuss here all these species and breeds.
In concluding these notes I leave off as I began,—with the
statement that any student of animal psychology who for any reason
whatever ignores or undervalues the intelligence of trained
animals puts a handicap upon himself.
