n.
Any of 17 species of crested parrots (subfamily Cacatuinae), found in Australia and from Malaya to the Solomon Islands.
Most species are white, with touches of red or yellow; some are black. All have a massive beak used to crack nuts, dig up roots, or pry grubs from wood; feeding is aided by a wormlike tongue. Treetop, hole-nesting birds, cockatoos at times form large, noisy flocks that damage crops. The largest cockatoo (the palm, or great black, cockatoo) is about 2530 in. (6575 cm) long. Some cockatoos live more than 50 years.
