About These Birds
East Brazilian Chachalaca
A medium-sized cracid (~550 g) of family Cracidae, endemic to northeastern and eastern Brazil. Inhabits the caatinga scrublands, cerrado woodland edges, and Atlantic Forest fragments. Forages in groups on fruits, seeds, and leaves. Least Concern; one of the few cracids adapted to Brazil's semi-arid caatinga biome and tolerant of disturbed habitats.
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.
