The White Cockatoo is around 46 cm (18 in) long, and weighs about 400 g (14 oz) for small females and up to 800 g (28 oz) for big males. The male White Cockatoo usually has a broader head and a bigger beak than the female. They have brown or black eyes and a dark grey beak. When mature some female White Cockatoos can have reddish/brown irises, while the irises of the adult male are dark brown or black. The feathers of the White Cockatoo are mostly white. However, both upper and lower surfaces of the inner half of the trailing edge of the large wing feathers are a yellow color. The yellow color on the underside of the wings is most notable because the yellow portion of the upper surface of the feather is covered by the white of the feather immediately medial (nearer to the body) and above. Similarly, areas of larger tail feathers that are covered by other tail feathers – and the innermost covered areas of the larger crest feathers – are yellow. Short white feathers grow from and closely cover the upper legs. The feathers of this species and others create a powder similar to talcum powder that easily transfers to clothing.
Food and feeding: In the wild, White Cockatoos feed on berries, seeds, nuts, fruit and roots. When nesting, they include insects and insect larvae.
Behaviour: White Cockatoos are kept as pets because they can be very affectionate, bond closely with people and are valued for their beauty. Cockatoos are also noisier than many parrots. They can become very bonded (or dependent) on human companion and this combined with their long life and often misunderstood behaviors can lead to behavior issues.. They have very strong beaks, and umbrellas are capable of breaking walnuts and fingers if very scared.
