The Greater Sulfur Crested Cockatoo (Cacatua galerita) is the largest and best known of all Cockatoos. It is white colored with the tail feathers and underside of the wings being yellow. When alarmed the cockatoo's crest opens up like a fan. These are large birds, measuring about twenty inches in length. This species has become a pest around urban and suburban areas because it often uses its powerful bill to destroy timber decking and siding on houses. Feeding normally takes place in groups, with one or more members watching for danger from a nearby perch.

The bird in this image was acting as such a lookout while the rest of his flock fed nearby. The sexes can be distinguished by the color of their eyes. Males have very dark blackish eyes, while the female's eyes are more brown. The bird shown here is a male, and was photographed in Dandenong Ranges National Park, Victoria, Australia.
