Olive-throated parakeet

The olive-throated parakeet ("Eupsittula nana"), also known as the olive-throated conure in aviculture, is a species of parrot in the family Psittacidae. It is found in forest and woodland in Jamaica, Mexico and Central America, and has been introduced to the Dominican Republic.
Description.
The species has a brown throat, with orange eyes in adults and brown eyes in juveniles. Its flight call is a noisy screech; it also utters harsh twittering sounds and piercing chirps. Measures and weighs .
Taxonomy and distribution.
The species occurs in two widely disjunct populations, with the nominate subspecies restricted to Jamaica, and the "astec" group (including subspecies "vicinalis") occurring from northeastern Mexico through the Yucatan Peninsula and along the Caribbean slope of Central America, as far south as northwestern Panama. The two populations are very similar. Most authorities consider them a single species; however, some have recommended splitting them, referring to the former as the Jamaican parakeet ("E. nana") and the latter as the Aztec parakeet ("E. astec").
The nominate subspecies has recently been discovered to occur in remote areas of Hispaniola as well, with genetic analysis suggesting it may have been introduced from Jamaica.
Habitat.
The parakeet inhabits wooded hills and mountain slopes, but also makes use of cultivated areas and scrubland in humid or semi-arid areas up to moderate elevations above sea level. It is most common at heights of around .
Ecology.
The parakeet feeds on buds and fruit as well as some crops, causing it to be considered a pest species in some areas. It reportedly nests only in arboreal termite nests found in trees of at least medium size.
