The Green-cheeked Parakeet is a South American forest parrot that gathers in flocks in the canopy and feeds on fruit and seeds.
Green cheeks are its signature feature. In the nominate subspecies, adults have gray or brown on the head, a chest patterned with gray, white, and brown, yellow or orange on the lower abdomen, and a long red tail. Average body length is 26 cm, and mass ranges from 62 to 81 g. Its eyes are brown with bare white rings, and its bill is gray or brown. Juveniles develop blue flight feathers, long tail feathers, and colorful abdominal feathers as they mature.
Active by day, it usually moves through the canopy in flocks of about 10 to 20. It eats fruit and seeds as well as flowers and nectar; some birds at higher elevations move downslope seasonally.
It nests in tree cavities. Both parents take turns incubating the eggs and feed and protect the young until they become independent.
