A cockatoo is any of the 21 parrot species having a place with the family Cacatuidae, the main family in the superfamily Cacatuoidea. Alongside the Psittacoidea (genuine parrots) and the Strigopoidea (huge New Zealand parrots), they make up the request Psittaciformes. The family has a predominantly Australasian conveyance, going from the Philippines and the eastern Indonesian islands of Wallacea to New Guinea, the Solomon Islands and Australia.
Cockatoos are unmistakable by the conspicuous peaks and bended bills. Their plumage is for the most part less beautiful than that of different parrots, being primarily white, dim or dark and frequently with shaded elements in the peak, cheeks or tail. On normal they are bigger than different parrots; in any case, the cockatiel, the littlest cockatoo species, is a little bird. The phylogenetic situation of the cockatiel stays unsettled, other than that it is probably the most punctual branch of the cockatoo ancestry. The leftover species are in two primary clades. The five huge dark shaded cockatoos of the sort Calyptorhynchus structure one branch. The second and bigger branch is framed by the sort Cacatua, involving 11 types of white-plumaged cockatoos and four monotypic genera that diverge prior; to be specific the pink and white Major Mitchell’s cockatoo, the pink and dark galah, the essentially dim posse group cockatoo and the enormous dark plumaged palm cockatoo.
Cockatoos like to eat seeds, tubers, corms, natural product, blossoms and bugs. They regularly feed in enormous groups, especially when ground-taking care of. Cockatoos are monogamous and home in tree hollows.
