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.
