[3][4] The brown-throated parakeet was formally described in 1758 by the Swedish naturalist Carl Linnaeus in the tenth edition of his Systema Naturae.

[5] The brown-throated parakeet is now one of five species placed in the genus Eupsittula that was introduced in 1853 by the French naturalist Charles Lucien Bonaparte.

Their breast is dull olive and their belly grass green with an orange patch in its center.

[9] More recent sightings in Puerto Rico and those in Florida, the British Virgin Islands, Anguilla, Dominica, and San Andrés are known or suspected to be of escaped or released cage birds rather than deliberate introductions or natural arrivals.

[14][15] Some populations on the mainland make seasonal movements and others are somewhat nomadic to follow the availability of food.

[8] The brown-throated parakeet's diet includes seeds, fruits, nuts, flowers, leaves, and sometimes insects.

Its flight calls "include high-pitched screeching and harsh grating 'scraart scraart' cries, rapidly repeated."

It has a very large range and its estimated population of at least five million mature individuals is believed to be stable.

Subspecies E. p. tortugensis, however, appears to be in decline, and the populations in mainland Venezuela are persecuted because they feed on crops.

[8] Nest poaching is a concern in island populations,[19] and in Venezuela both young and adult individuals are locally traded as cage birds for the pet market.
