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.

Inhabits cloud forests and humid montane forests in the highlands of Mexico, Guatemala, Honduras, El Salvador, and Nicaragua. Arboreal frugivore. Vulnerable due to deforestation and hunting in the fragmented highlands of Mesoamerica.
