Rusty-faced Parrot

A medium-sized parrot of the high-altitude cloud forests and Andean slopes of Colombia and Venezuela, rusty-faced parrots have green plumage with a distinctive orange-rufous face and forehead. They inhabit humid mountain forests between 1,500–3,000 meters and are little studied due to their remote, steep habitat. Listed as Vulnerable due to ongoing deforestation of Andean cloud forests. They move seasonally with food availability across forested ridges.
