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 Psittacula was introduced in 1800 by the French naturalist Georges Cuvier. [1] The type species was designated in 1923 by Gregory Mathews as the red-breasted parakeet. [2] [3] The name of the genus is a diminutive of the Latin word psittacus for a "parrot". [4] The genus includes 16 species, of which three are extinct. [5]

Psittacopasseres is a taxon of birds consisting of the Passeriformes (passerines, a large group of perching birds) and Psittaciformes (). [3] Per Ericson and colleagues, in analysing genomic DNA, revealed a lineage comprising passerines, psittacines and Falconiformes. [4]
The true parrots are distributed throughout the tropical and subtropical regions of the world, mostly in the Southern Hemisphere, covering many different habitats, from the humid tropical forests to deserts in Australia, India, Southeast Asia, sub-Saharan Africa, Central and South America, and two species, one extinct (the Carolina parakeet), formerly in the United States.
