Parrots are birds of the roughly 350 species in the order Psittaciformes, found in most warm and tropical regions.

Also known as psittacines, they are usually grouped into two families: the Psittacidae (true parrots) and the Cacatuidae (cockatoos).

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. Most parrots are monomorphic or minimally sexually dimorphic.
