The Groove-billed Ani
(C. sulcirostris), which is so named from the presence of several distinct longitudinal grooves on the upper mandible, extends from the lower Rio Grande Valley in Texas and Lower California to Peru, while the Great Ani (C. major) is found only in South America; it is distinguished at once by its large size, its total length being from eighteen to twenty inches as against twelve or thirteen in the other species and more glossy plumage. The habits of these are similar to those of the Black Ani.
