The green parakeet is a medium-sized parrot native to Central America, from the southernmost tip of Texas south to northern Nicaragua. This species was formerly placed in the genus Aratinga as A. holochlora, and divided into various subspecies. Later, it was split into three species as green conure, pacific conure, and Socorro conure. Today it is recognised as single species with a highly threatened subspecies endemic to Socorro in the Revillagigedo Islands, Mexico.
Description
The bird is 32 cm in length, and is mostly green in color. It also has a yellow beak. The bird feeds on seeds, various fruits, and corn. It can sometimes be considered a crop pest. Wild birds primarily use scrub and swamp forests, woodlands, and forest clearings. The US population takes advantage of palm groves in cities.
Ecology
Green parakeet pairs usually find holes in trees in which to nest, where the female lays three or four eggs. It also nests colonially in crevices on cliff faces. After the breeding season is completed, the birds form large communal roosts.
Distribution
The species occurs from southern Texas and northern Mexico south through the Middle American isthmus to southwestern Nicaragua. It inhabits a variety of woody habitats. In western Nicaragua, their nesting sites lie within the El Chocoyero - El BrujoProtected Area, but the birds still face threats from the outside world when they leave the reserve to feed. The A. brevipes subspecies is highly threatened by habitat loss due to feral sheep and predation by feral cats. Surveys from 2006 and 2007 estimated a population around 300 individuals, suggesting a population decline from previous population estimates. The status of populations in southern Texas is unclear, with some claiming them to be feral escapees. However, the groups in the Rio Grande Valley are now generally regarded as naturally occurring because of the proximity of confirmed native populations, the deforestation of Tamaulipas which forced them to disperse, and earlier evidence from 1911 of these parakeets consuming a strawberry harvest at Combs. It has become an invasive speciesaround the world, as well. It has been sighted in the Iberian peninsula, probably of birds that escaped from their owners and return to the wild.
