Small, vocal white cockatoo with an erectile crest. Primarily white with a small pink patch in front of the eye. Very conspicuous, and often forms large, noisy flocks (up to several thousand birds) around water sources. Roosts in trees and nests in hollows, but primarily feeds on the ground. Well known for its comical antics; they often appear to play with one another. Typically loud, with a slurred multi-note falsetto call.
