From Wikipedia, the free encyclopedia
The genus Pezoporus contains two Australian species: the Night Parrot (Pezoporus occidentalis) and the Ground Parrot (Pezoporus wallicus). The former species was previously separated in a distinct genus, Geopsittacus. It is considered a part of the tribe Platycercini or, if this is considered a subfamily, the monotypic tribe Pezoporini. Its closest relatives are some other small broad-tailed parrots of the genus Neophema, and perhaps the Budgerigar (Melopsittacus undulatus), and modern research suggests that the genus should not be considered a tribe of its own but included with these, if the broad-tailed parrots are raised to subfamily status (Christidis et al., 1991; Leeton et al., 1994).
