A large white or colorful parrot with a prominent crest, native to Australia and nearby regions.
From Malay kakak tua (old sister), the Malay name for the bird. Entered Portuguese as cacatua, then spread to European languages through colonial trade in the East Indies.
The cockatoo's name literally means 'old sister' in Malay—which might seem odd until you realize these birds live 50-60 years and were respected as wise elders in island cultures.
