HABITS. This interesting species appears to be common in Western Texas, the valley of the Rio Grande, and Western Mexico. It was met with in these regions on the several railroad surveys, and is described by Dr. Heermann as possessing musical powers surpassed by few other birds. When alarmed it immediately hides itself in a thick covert of underbrush, whence it is almost impossible to dislodge it. Its food consists of fruit and berries when in their season, of insects and their larvæ, and of worms. These it collects both among the trees and from the ground, on the latter of which it spends much of its time. Mr. J. H. Clark states that the nest of this bird is very similar to that of the Mocking-Bird, but is finer and much more compact. He adds that it is oftener found among the _Opuntia_ than elsewhere. It is a quiet bird, rather shy, and keeps closely within the clumps of the chaparral. For a bird of its size it makes an unusual noise in flying. At Ringgold Barracks Mr. Clark’s tent was pitched under a como-tree in which there was a nest of these birds. They were at first shy and seemed quite disposed to abandon their nest, but, however, soon became accustomed to their new neighbor, and went on with their parental duties. The position of their nest had been very judiciously selected, for it was during the season of the black fruit of the como, which is somewhat in the shape and size of a thimble, with a pleasant milky pulp. These constituted their principal food. The eggs in this nest were five in number. Lieutenant Couch met with it from Brownsville to Durango, where it had already paired as early as February. He describes it as exceedingly tame and gentle in its habits, and with a song remarkably melodious and attractive. Perched on the topmost bough of a flowering mimosa, in the presence of his consort, the male will pour forth a volume of most enchanting music. Their nest is generally very nearly flat, measuring nearly six inches in circumference, and scarcely more than an inch in its greatest thickness. It has hardly any distinct cavity, and hollows but very slightly from the rim to the centre, its greatest depression having barely the depth of half an inch. The nests are composed of long coarse fibrous roots, rudely, but somewhat compactly interwoven. The inner framework is constructed of the same materials intermixed with the finer stems of grasses. Mr. H. E. Dresser states that in the vicinity of Matamoras these birds are fond of frequenting small villages, and that he frequently found their nests within the gardens and court-yards of the houses, and near the road. The eggs of this Thrush vary considerably in size, ranging from 1.20 to 1.03 inches in length, and from .84 to .77 of an inch in breadth. Their mean length is 1.12 inches, and their average breadth .80. They have a light green ground-color, generally, though not thickly, covered with fine brown spots.
