311. Chachalaca. Ortalis vetula mccalli.

Range.--Eastern portions of Mexico, north to the Lower Rio Grande Valley in Texas.

A very peculiar grayish colored bird with a greenish gloss to the back, and a long, broad tail, quite long legs, and with the face and sides of the throat devoid of feathers. They are very abundant birds in some localities, and very noisy during the breeding season, their notes resembling a harsh trumpeting repetition of their name. They are ground inhabiting birds, but nest in low bushes. Their nests are made of sticks, twigs, leaves, or moss and are generally frail, flat structures only a few feet above the ground. During April, they lay from three to five buffy white eggs, the shell of which is very rough and hard. Size 2.25 × 1.55.
