About These Birds
Black Guan
A medium-large cracid (~1.1 kg) of family Cracidae, entirely sooty-black with blue facial skin. Endemic to montane cloud forests of Costa Rica and western Panama at 1,200–3,000 m elevation. Arboreal frugivore, feeding on berries and small fruits. Least Concern; restricted range but relatively common within Costa Rican Talamanca highlands and well represented in protected areas.
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.
