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.
Helmeted Curassow
A large cracid (~3.2 kg) of family Cracidae, bearing a remarkable light blue casque on the forehead. Inhabits humid montane forests of the Andes in Colombia and Venezuela at 600–2,000 m elevation. Forages on the forest floor for fallen fruits, seeds, and invertebrates. Vulnerable due to deforestation of Andean forests and heavy hunting pressure for its substantial meat.
