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 dest.i.tute 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 s.p.a.ce 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.

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 woodp.e.c.k.e.r 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 a.s.sume 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 gra.s.s 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 gra.s.s 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 ma.s.s 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."

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 p.r.o.nounced 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 c.o.c.katoos 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 a.s.sociate 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 peac.o.c.k 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 c.o.c.katoos. 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 apt.i.tude 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 a.s.sociation 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 c.o.c.katoos, the macaws, and the various others previously mentioned.

It is safe to a.s.sert 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 (_Ca.s.sidix_), 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 _Ca.s.sidix._ 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.
