Cockatoos

　　Abeera Zamad A cockatoo is any of the 21 species belonging to the bird family Cacatuidae. Along with the Psittacidae (the true parrots) and the Strigopidae (the large New Zealand parrots), they make up the parrot order Psittaciformes. Placement of the cockatoos as a separate family is fairly undisputed, although many aspects of the other living lineages of parrots are unresolved. The family has a mainly Australasian distribution, ranging from the Philippines and the eastern Indonesian islands of Wallacea to New Guinea, the Solomon Islands and Australia.
