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.
White-browed Guan
A large cracid (~1.4 kg) of family Cracidae, with a prominent white supercilium. Endemic to the caatinga scrublands and dry forests of northeastern Brazil. Inhabits dry deciduous forests, gallery forest, and scrubby vegetation. Arboreal frugivore. Vulnerable; one of the few large cracids adapted to Brazil's semi-arid caatinga, threatened by habitat loss and hunting.
