Systemics

The following classification is a version in which several subfamilies are recognized. Molecular data suggests that several subfamilies might indeed be valid and perhaps even be elevated to family rank, but the arrangement of tribes in these is not well resolved at present.

Parrots

Parrots are birds of the roughly 350 species in 85 genera comprising the order Psittaciformes, found in most warm and tropical regions. Characteristic features of parrots include a strong curved bill, an upright stance, strong legs, and clawed zygodactyl feet. Most parrots are predominantly green, with other bright colors, and some species are multi-colored. Cockatoo species range from mostly white to mostly black, and have a mobile crest of feathers on the top of their heads.
