The plain chachalaca (Ortalis vetula) is a large bird in the family Cracidae. It breeds in tropical and subtropical environments from mezquital thickets in the Rio Grande Valley in southernmost Texas, United States to northernmost Costa Rica.
In Central America, this species occurs in the Pacific lowlands from Chiapas, Mexico to northern Nicaragua and as a separate population in Costa Rica, where its range is separated by a short distance, as a disjunct population.
The plain chachalaca is 56 cm (22 in) long and has a mass of 0.65 kg (1.4 lb). It is long-necked with a small head and bare throat. Adults have a greyish head and neck with a dull olive-brown body and wings. The underbelly is pale to ochraceous and the tail is blackish with green gloss and buffy-white tip. The iris is brown and bill is black; orbital skin and the feet are dull grey.
This species frequents dry and moist forests, especially where interspersed with scrub and savanna. Usually found in groups of up to 15 birds, the plain chachalaca is furtive and wary and prefers to escape from danger by running swiftly on the ground or leaping and gliding through brushy tangles.
The plain chachalaca feeds in trees or on the ground on fruit (figs, palms, Sapotaceae), seeds, leaves, and flowers. It is sometimes a pest of crops such as tomatoes and cucumbers.
