Tweet of the Day - Sulphur-crested Cockatoo
Download Sulphur-crested Cockatoo
Tweet of the Day is the voice of birds and our relationship with them, from around the world.
Liz Bonnin presents the raucous calling sulphur-crested cockatoo from Australia. It is with somewhat heavy irony that with its loud, jarring calls, the sulphur crested cockatoo is also known as the "Australian Nightingale". These large white parrots with their formidable curved beaks and long yellow crests which they fan out when excited are familiar aviary birds. One of the reasons that they're popular as cage birds is that they can mimic the human voice and can live to a great age. A bird known as Cocky Bennett from Sydney lived until he was a hundred years old, although by the time he died in the early 1900s he was completely bald, and was then stuffed for posterity. In its native forests of Australia and New Guinea, those far-carrying calls are perfect for keeping cockatoo flocks together. They're highly intelligent birds and when they feed, at least one will act as a sentinel ready to sound the alarm in case of danger. So well-known is this behaviour that in Australia, someone asked to keep a lookout during illegal gambling sessions is sometimes known as a "cockatoo" or "cocky".
