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.
Yungas Guan
A large cracid (~1.8 kg) of family Cracidae, inhabiting the Yungas humid montane forests of Bolivia and Argentina. Closely related to Dusky-legged Guan and sometimes treated as a subspecies. Arboreal, feeding on fruits and seeds in cloud forest at 500–2,000 m elevation. Not Evaluated independently by IUCN; taxonomy under review, with population status unclear due to limited survey data.
