About These Birds
Sickle-winged Guan
A medium-sized cracid (~700 g) of family Cracidae, with sickle-shaped outer primaries and blue facial skin. Inhabits humid Andean cloud forests and forest edges from Colombia to Bolivia at 900–3,000 m elevation. Arboreal, feeding mainly on small fruits and berries. Least Concern; widely distributed in the Andean cloud forest zone and common in undisturbed montane habitats.
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.
