About These Birds
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.

Arboreal, feeding on fruits, seeds, and buds in the canopy. Least Concern; restricted to Andean cloud forest but common within its range and tolerates some forest disturbance.
