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.

Vulnerable; one of the few large cracids adapted to Brazil's semi-arid caatinga, threatened by habitat loss and hunting.
