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."
