Cockatoo

 A cockatoo is any of the 21 parrot species having a place with the family Cacatuidae, the lone family in the superfamily Cacatuoidea. Alongside the Psittacidae (genuine parrots) and the Strigopoidea (enormous New Zealand parrots), they make up the request Psittaciformes. The family has a mostly Australasian appropriation, going from the Philippines and the eastern Indonesian islands of Wallacea to New Guinea, the Solomon Islands and Australia. 

Cockatoos are conspicuous by their unmistakable peaks and bent bills. Their plumage is by and large less bright than that of different parrots, being for the most part white, dim or dark and frequently with hued highlights in the peak, cheeks or tail. On normal they are bigger than different parrots; be that as it may, the cockatiel, the littlest cockatoo species, is a little bird. The phylogenetic situation of the cockatiel stays unsettled, other than that it is perhaps the most punctual branch of the cockatoo genealogy. The leftover species are in two primary clades. The five enormous dark shaded cockatoos of the variety Calyptorhynchus structure one branch. The second and bigger branch is shaped by the variety Cacatua, involving 11 types of white-plumaged cockatoos and four monotypic genera that expand prior; specifically the pink and white Major Mitchell's cockatoo, the pink and dark galah, the fundamentally dim posse pack cockatoo and the enormous dark plumaged palm cockatoo. 

Cockatoos like to eat seeds, tubers, corms, organic products, blossoms and bugs. They frequently feed in enormous groups, especially when ground-taking care of. Cockatoos are monogamous and home in tree hollows. Some cockatoo species have been unfavourably influenced by territory misfortune, especially from a lack of reasonable settling hollows after enormous development trees are cleared; then again, a few animal types have adjusted well to human changes and are viewed as farming bugs. 

Cockatoos are famous birds in aviculture, however, their requirements are hard to meet. The cockatiel is the simplest cockatoo species to keep up with and is by a long shot the most habitually kept in bondage. White cockatoos are more normally found in bondage than dark cockatoos. Illicit exchange of wild-got birds adds to the decrease of some cockatoo species in nature.
