About These Birds
Colombian Chachalaca
A medium-sized cracid (~487 g) of family Cracidae, endemic to the Cauca and Magdalena river valleys of Colombia. Inhabits dry forest edges, gallery woodlands, and scrubby vegetation at low to mid elevations. Forages in social groups for fruits, seeds, and leaves. Least Concern; though endemic to Colombia, it is common within its restricted range and adapts to modified 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.
