About These Birds
Rufous-headed Chachalaca
A medium-sized cracid (~630 g) of family Cracidae, with a striking rufous head. Inhabits humid and deciduous forests, forest edges, and scrub in western Ecuador and northwestern Peru. Feeds on fruits and leaves in the forest understory and canopy. Vulnerable due to extensive deforestation in the Tumbesian region, one of the world's most threatened biodiversity hotspots.
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.
