About These Birds
Chaco Chachalaca
A medium-sized cracid (~580 g) of family Cracidae, with grey neck and olive-brown plumage. Inhabits the dry woodlands, gallery forests, and thorn scrub of the Gran Chaco region across Bolivia, Paraguay, Brazil, and Argentina. Feeds in social groups on fruits, leaves, and seeds. Least Concern; broadly distributed across the Chaco, tolerating degraded and secondary 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.
