The Olive-throated Parakeet (Eupsittula nana astec), also known as the Olive-throated Conure in aviculture, is a species of bird in subfamily Arinae of the family Psittacidae, the African and New World parrots. It is found from Mexico to Costa Rica and in Jamaica; it has been introduced to the Dominican Republic on Hispaniola. These parakeets are fairly small parrots, usually with a relatively long and somewhat pointed tail. This species is fairly common in tropical lowlands, mainly in semi-open areas with scattered trees, woodland, locally in towns and suburban areas. Often in small flocks, also in pairs. Note the dirty brownish cast to the breast, and the whitish eyering. In most parts of its range, no other parakeets occur.
The "Jamaican" olive-throated parakeet E. n. nana is the nominate subspecies; it is 22 to 26 cm (8.7 to 10 in) long and weighs about 72 to 85 g (2.5 to 3.0 oz). The "Aztec" olive-throated parakeet is 21.5 to 25 cm (8.5 to 9.8 in) long and weighs about 85 g (3.0 oz). The sexes are alike. Adults of the nominate subspecies have a mainly dark green head and upperparts with yellowish ear coverts and rump. Bare white skin surrounds their eye. Their throat and breast are olive-brown that becomes olive on the belly and vent. Their wings are mostly green with dull blue on the upper side of the flight feathers and gray on their underside. Their tail's upper surface is green and its underside is yellowish. Their bill is browish horn color with a paler tip, their iris yellow to orange, and their legs blackish gray. Immature birds are similar to adults.
Subspecies E. n. astec ("Aztec" in part) has paler olive-brown underparts, especially on the belly and vent. Subspecies E. n. vicinalis is slightly larger than astec and is brighter green above and greener below
