About These Birds
Alagoas Curassow
A large cracid (~2.9 kg) of family Cracidae, with glossy black plumage and a distinctive red knobbed bill. Extinct in the Wild; the last wild individuals disappeared from Alagoas, Brazil by the 1980s due to deforestation of the Atlantic Forest. A captive population survives in Brazilian zoos, with reintroduction programs underway. One of the most critically imperiled birds globally.
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.
