About These Birds
Rufous-headed Chachalaca
A medium-sized cracid (~495 g) of family Cracidae, with a rufous crown and head. Endemic to northeastern Brazil, primarily found in caatinga scrubland and dry forest habitats. Forages on fruits and vegetation in small groups. Not Evaluated by IUCN; taxonomy is debated as it may represent a subspecies or synonym of related chachalaca taxa. Little studied in the wild.
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.
