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.
Cauca Guan
A medium-large cracid (~1.2 kg) of family Cracidae, with olive-brown plumage and a red throat wattle. Endemic to the upper Cauca Valley of Colombia at 1,200–2,400 m elevation. Inhabits remnant humid Andean forests. Arboreal, feeding on fruits and seeds. Vulnerable due to severe deforestation in one of Colombia's most densely populated valleys and ongoing hunting pressure.
