The Yellow-chevroned Parakeet (Brotogeris chiriri) is a species of bird native to tropical South America south of the Amazon River basin from central Brazil to southern Bolivia, Paraguay and northern Argentina. Some birds that have been released into the wild from captivity have established self-sustaining populations in the cities of Los Angeles and San Francisco, California and Miami, Florida. It is also established in the downtown area of Rio De Janeiro, Brazil, where it had been introduced.
The adult is 7.9 to 9.8 inches in length, and is mostly light green in color. It has a trailing edge on its folded wings that is also seen in flight. This species was considered to be the same species as the Canary-winged Parakeet until 1997.
This bird feeds mainly on seeds and fruit in its native habitat. The feral populations that exist elsewhere have adapted to take in blossoms and nectar. Feral birds will also come to bird feeders. Wild birds primarily use disturbed forest and forest clearings near settlements. It is rarely seen feeding in deep tropical forest.
This species usually nests in a hole in tree. It also forms nesting tunnels in dead palm fronds. The female lays 4 to 5 eggs. Once the young are raised and fledge the nest, all birds will form a large communal roost until the next breeding season.
