About These Birds
Rufous-headed Chachalaca
A medium-sized cracid (~495 g) of family Cracidae, with a rufous crown and head. Endemic to northeastern Brazil, primarily found in caatinga scrubland and dry forest habitats. Forages on fruits and vegetation in small groups. Not Evaluated by IUCN; taxonomy is debated as it may represent a subspecies or synonym of related chachalaca taxa. Little studied in the wild.
Band-tailed Guan
A medium-sized cracid (~800 g) of family Cracidae, with a distinctive pale-tipped tail band. Inhabits montane humid forests in the Sierra Nevada de Santa Marta and Andes of Colombia and Venezuela. Arboreal, feeding on fruits, seeds, and buds in the canopy. Least Concern; restricted to Andean cloud forest but common within its range and tolerates some forest disturbance.
