About These Birds
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.
Rusty-margined Guan
A medium-sized cracid (~950 g) of family Cracidae, with rusty-brown wing margins and a red wattle. Inhabits Atlantic Forest, cerrado woodland edges, and humid forests in eastern and central Brazil and bordering countries. Feeds on fruits, leaves, and seeds in forest canopy. Near Threatened due to Atlantic Forest loss and hunting; one of the most common guans in its range.
