psittaciform summary

psittaciform, Any member of Psittaciformes, an order of more than 360 species of brightly coloured noisy birds. Most researchers recognize only one family, Psittacidae, and several subfamilies that include parakeets (including budgerigars, rosellas, and conures), lovebirds, amazons, macaws, and parrotlets (or parrolets). Members of the cockatoo subfamily, Cacatuinae, live primarily in Australia, New Guinea, and the Philippines. Parrots are primarily birds of the tropics. Their distribution encompasses the tropical and southern temperate regions of the world, including Madagascar, many Pacific islands, and the West Indies. In Asia they occur throughout almost all of India but extend northward only to the Himalayas and southern China; they are absent from Europe. In North America one species, the thick-billed parrot (Rhynchopsitta pachyrhyncha), which inhabits mountainous areas of western Mexico, once ranged north into the extreme southwestern U.S.
