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.
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.
