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.
Scaled Chachalaca
A medium-sized cracid (~560 g) of family Cracidae, with scaly patterning on the neck and upper breast. Endemic to southeastern Brazil, inhabiting Atlantic Forest and its edges, humid lowland forests, and secondary vegetation. Forages in groups for fruits and seeds in the forest canopy. Least Concern; restricted to one of the world's most threatened biomes but adaptable to degraded habitats.
