Chachalacas

Chachalacas — Chachalacas, genus Ortalis, are ground-feeding turkey like birds so named because of their loud, harsh calls, which sound like cha-cha-la-ca. They are commonly found in wooded areas throughout South and Central America. The Plain Chachalaca, Ortalis vetula is a large bird in the Cracidae family. It breeds in tropical and subtropical environments from the chaparral thickets along the Rio Grande River in southernmost Texas, USA , (named locally the ’Rio Grande Valley’), 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″) long and weighs 650 g (1 lb 7 oz). 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 are 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 tropical dry and moist forest, 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.

The call is a loud, raucous RAW-pa-haw or cha-cha-LAW-ka, often by several birds in a rhytmical chorus, especially in early morning and evening, usually from well up in trees. It also produces peeping whistles and cackles.
