About These Birds
Rufous-headed Chachalaca
A medium-sized cracid (~630 g) of family Cracidae, with a striking rufous head. Inhabits humid and deciduous forests, forest edges, and scrub in western Ecuador and northwestern Peru. Feeds on fruits and leaves in the forest understory and canopy. Vulnerable due to extensive deforestation in the Tumbesian region, one of the world's most threatened biodiversity hotspots.

A medium-sized cracid (~560 g) of family Cracidae, olive-brown with a bare red throat patch. Inhabits thickets, forest edges, and riparian woodlands from southern Texas through Mexico to Costa Rica. Social and noisy, roosting and foraging in groups on fruits, leaves, and seeds. Least Concern; extremely vocal at dawn with a raucous "cha-cha-lac" call.
