A rather small corella-type cockatoo. An entirely white, short-tailed, noisy parrot with light blue bare skin around the eyes. Chest and belly often stained slightly brownish. Undertail and underwing yellowish in flight, but difficult to see. Often raises tall white crest. Found in most types of forest up to 1700 meters of elevation. Unmistakable within its range. Voice loud and obtrusive, including a harsh croaking “reh-reh.”
