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.
Nocturnal Curassow
A medium-large cracid (~1.4 kg) of family Cracidae, the only curassow known for crepuscular and nocturnal activity. Has reddish-brown barred plumage and a small crest. Inhabits humid lowland rainforest in the western Amazon basin in Colombia, Ecuador, Peru, and Brazil. Feeds on fruits and invertebrates. Least Concern; secretive behavior and dense forest habitat provide natural protection.
