This bird is especially remarkable for great swiftness of foot, and in fact appears to be almost unrivalled in that respect by any other of our North American species, not even excepting the Grouse, Partridges, or any other of the smaller gallinaceous birds. These, though possessing the ability to run short distances very swiftly, are incapable of sustaining a protracted chase like the present bird. In Mexico, and the adjacent portions of the United States, it is not unusual, as a matter of amusement, to try the speed of our bird by pursuing him on horseback, or by chasing him with dogs, under which severe test of his fleetness, he acquits himself very creditably, and makes, as we shall see presently, a longer race than is usually expected by his pursuer. He evidently possesses both speed and bottom, unrivalled by any fair competition in ornithological pedestrianism, so far as its annals are chronicled, or the present writer’s information on that subject extends.
Clothed in plumage of agreeable and unusual colors for a Northern species, and habitually frequenting the ground, walking or running with its long tail carried erect, and assuming a variety of grotesque attitudes, it is not surprising that this bird has attracted the attention of nearly all our naturalists and travellers who have visited its native regions. Through their exertions, it is now to be found in nearly all our museums and private collections, and many facts respecting it have been placed on record.
Though terrestrial in its habits, and exhibiting in some degree the manners and habits of the gallinaceous birds (the Pheasants, Partridges, Grouse, &c.), this bird is by no means to be classed in that division of the ornithological kingdom. It is a Cuckoo, and a relative of the celebrated bird of Europe so long known as to have become classic, and of the unobtrusive and plain-plumaged little birds of the United States, of the genus Coccyzus, popularly known by the name of Cow-birds, or Rain-birds. Our present bird is a representative of the gallinaceous form, in the family of Cuckoos. Throughout the animal and vegetable kingdoms, and in every division or subdivision of whatever character, five primary groups or forms present themselves. In birds and all their groups, these are: the typical, or bird-like form; the predatory, or rapacious; the gallinaceous, or walking; the grallatorial, or wading; and the natatorial, or swimming form. In the group of Cuckoos, which is quite extensive, and species of which are found in nearly all parts of the world, the bird now before us belongs to the subdivision comprising the gallinaceous or walking Cuckoos, and is a striking example of that peculiar form in the great circle of birds, and of the prevalence of a law which is universal, and not difficult to demonstrate.
The first American naturalist who observed the bird now before the reader, was Dr. William Gambel, and a description by him will be found in the Proceedings of the Academy of Natural Sciences of Philadelphia, Vol. II., p. 263. (1845). Subsequently, it has been noticed by nearly all naturalists who have visited California, New Mexico, or Texas, and interesting contributions to its history are contained in their publications relating to the ornithology of those countries.
Our esteemed friend, Col. George A. McCall, with his usual clearness and scientific accuracy, gave the first satisfactory account of this bird, in the Proceedings of the Philadelphia Academy, III. p. 234 (July, 1847.):
“Although the toes of this bird are disposed in opposite pairs, as in other species of his family, yet the outer toe being reversible, and of great flexibility, is in either position aptly applied in climbing or perching, as well as on the ground. Thus he at times pitches along the ground in irregular but vigorous hops; and again, when the outer toe is thrown forward, he runs smoothly, and with such velocity, as to be able to elude a dog in the chaparral, without taking wing. He feeds on coleoptera, and almost every description of insects, and near the river Nueces, where the snail (Lynnæus stagnalis) abounds, it is also greedily eaten. These he snatches from the ground, or plucks from the low branch of a bush; and as he rarely wanders far from his abode, the prize is carried to a particular spot, where the shell is broken with his strong bill, and the animal devoured. Piles of these shells are often found that would fill half a hat crown.
“Although dwelling principally on the ground, he is ready and expert in catching his prey in the air, in which act his movements are full of animation,—bounding from the ground with a sudden impulse to the height of eight or ten feet; his wings and tail are seen expanded for a scarcely appreciable instant, and his bill is heard to snap as he takes his prey, when he drops as suddenly to the spot from which he sprang. Here he will stand for a moment, his legs apart, and his tail flirted on one side with a wild and eccentric expression of exultation in his attitude, before he scampers off under cover of the thick chaparral. At first, I thought,—as is the general impression among the Mexicans,—that his powers of flight were extremely limited; but he will, when suddenly alarmed in open ground, rise with a light, quick motion, and continue his flight over the bushes for some hundred yards, apparently with an ease that would argue the ability to sustain a longer flight.
“Though fond of solitude and shade, he will, at an early hour in the morning, climb to the top of a straight leafless branch, there to sit and enjoy the first rays of the sun.
“He is said by the Mexican rancheros to build his nest of loose sticks, either in a low, thick bush, or in close cover on the ground. The eggs are said by them to be two or three in number, and of a whitish color.”
We have again to express our obligations to Col. McCall for the following contribution to our present article:—
