Mr. A. J. Grayson had one of these birds in confinement, which became quite tame, and readily fed upon any kind of raw meat, but preferred lizards and small birds, the latter of which it swallowed, feathers and all. If given to him alive, he would play with them awhile before swallowing them, as a cat does with a mouse. They are sometimes tamed, and kept about gardens to kill mice and insects. Dr. Kennerly also states that when taken alive they soon become quite tame, and willingly remain about a house, soon destroying all the mice in the vicinity, which they catch with as much dexterity as a cat.
Mr. Dresser found this bird abundant throughout the mesquite regions, and more particularly so near the Rio Grande. He found its eggs near San Antonio in April and May, and received them even as late as the 23d of September. They build a clumsy nest of mesquite twigs, placed at some height on a bough or in a hollow tree, and lay from two to four pure white eggs. The stomachs examined by Mr. Dresser were found to contain small snakes, lizards, and ticks. He had one in a semi-domesticated state at Matamoras, which became very tame, and was so mischievous that he could not let it remain in the house. It would steal and hide everything that it could carry off, and was particularly fond of tearing up letters and upsetting the inkstand. It was never caged or tied up, and would frequently pay the neighbors a visit, always returning before evening. He fed it on raw meat and lizards. It flew with great ease, and was very fond of perching on the house-top. This bird had a singular antipathy to a tame parrot, and whenever the latter was let out of the cage, it would get into a rage, and either go to the house-top or decamp to some of the neighbors.
The eggs are white, of a rounded oval, equal at either end, and measure 1.60 by 1.22 inches.
Genus COCCYGUS, Vieillot.
Coccyzus, Vieillot, Analyse, 1816. (Type, Cuculus americanus, Linn.)
Erythrophrys, Swainson, Class. Birds, II, 1837, 322.
Gen. Char. Head without crest; feathers about base of bill soft; bill nearly as long as the head, decurved, slender, and attenuated towards the end. Nostrils linear. Wings lengthened, reaching the middle of the tail; the tertials short. Tail of ten graduated feathers. Feet weak; tarsi shorter than the middle toe.
The species of Coccygus are readily distinguished from those of Geococcyx by their arboreal habits, confining themselves mainly to trees, instead of living habitually on the ground. The plumage is soft, fine, and compact.
The American Cuckoos differ from the European (Cuculus) by having lengthened naked tarsi, instead of very short feathered ones. The nostrils, too, are elongated instead of rounded. The habits of the two are entirely different, the American species rearing their own young, instead of laying the eggs in the nests of other birds, like the European Cuckoo and the American Cowbird (Molothrus pecoris).
