The plain chachalaca is a bird of Mexico and Central America and in the US it occurs only in the lower Rio Grande Valley. Where it does occur it is extremely conspicuous because of its large size, long tail, and (especially) its raucous loud calls -- the source of its unusual common name. This bird was photographed at Sabal Palm Sanctuary near Brownsville, Texas.
