About These Birds
Yellow-knobbed Curassow
A large cracid (~2.4 kg) of family Cracidae, males black with a yellow knob at the bill base and curly crest. Found in tropical dry forests, gallery forests, and forest edges in Venezuela and adjacent Colombia. Forages on the ground and in low vegetation for fruits and seeds. Near Threatened due to habitat loss and hunting in Venezuela's increasingly degraded lowland forests.
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.
