The Triton Cockatoo is one of the world's largest cockatoos. They are a large parrot that measures an average 18 inches (46 centimetres) and weighs approximately 693 grams at maturity. Males are generally larger than females. Like most cockatoos the Triton has stunning white plumage with a striking yellow crest. Yellow feathers may also be seen under its tail and wings.

The Triton Cockatoo is also big on personality. They are generally very affectionate to their owners and seem to have an endless love of being handled. In fact, some will even demand attention. These are not birds for people with little time to give. They require a great deal of time and attention and should never be considered for a home where they will spend most of their time alone.  They are most often loudest in the evening and in the morning. They are quite vocal and many learn to talk, though they are best known for their intelligence.

The Triton Cockatoo is able to learn many tricks. That, combined with their lively personalities, makes the Triton Cockatoo very entertaining.  Triton Cockatoos should be given plenty of toys, particularly those they can chew. In addition, they should be given plenty of wooden perches to both climb and chew.

Tritons are known to form close bonds with their owners and are generally not nervous parrots, though they may be more nervous than the Greater Sulphur Crested Cockatoo.
