About These Birds
Andean Guan
A medium-sized cracid (~650 g) of family Cracidae, with dull brown-olive plumage and a bare red throat wattle. Inhabits Andean cloud forests and forest edges from Venezuela south to Bolivia at elevations of 1,200–3,500 m. Feeds on fruits, seeds, and invertebrates. Least Concern; widespread in montane Andes and one of the more commonly encountered Penelope guans.
White-crested Guan
A large cracid (~1.3 kg) of family Cracidae, with a distinctive white crest on the crown. Endemic to the eastern Amazon basin in central and northeastern Brazil. Inhabits humid terra firme and várzea forests. Arboreal frugivore, feeding on fruits and seeds in the canopy. Vulnerable due to ongoing deforestation and hunting in the Amazon; relies on intact primary forest.
