Parrots (Psittaciformes), also known as psittacines (/ ˈ s ɪ t ə s aɪ n z /), [1] [2] are birds with a strong curved beak, upright stance, and clawed feet. [ a ] They are classified in four families that contain roughly 410 species in 101 genera , found mostly in tropical and subtropical regions.

The genus Eupsittula was introduced in 1853 by the French naturalist Charles Lucien Bonaparte with the orange-fronted parakeet as the type species. [3] [4] The genus name combines the Ancient Greek eu meaning "good" with the Modern Latin psittula meaning "little parrot". [5] The genus contains five species. [6]
The following cladogram shows how the family Psittaculidae relates to the three other families in the order Psittaciformes.The tree is based on the work by Leo Joseph and collaborators published in 2012 but with the choice of families and the number of species in each family taken from the list maintained by Frank Gill, Pamela Rasmussen and David Donsker on behalf of the International ...
