About These Birds
East Brazilian Chachalaca
A medium-sized cracid (~550 g) of family Cracidae, endemic to northeastern and eastern Brazil. Inhabits the caatinga scrublands, cerrado woodland edges, and Atlantic Forest fragments. Forages in groups on fruits, seeds, and leaves. Least Concern; one of the few cracids adapted to Brazil's semi-arid caatinga biome and tolerant of disturbed habitats.
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.
