Cockatoos are extremely intelligent and curious birds. They are affectionate with people and demand a lot of attention and stimulation. Sid, a sulphur-crested cockatoo, is no different and he closely examines and greets new guests. He climbs on Dave's arm and inspects him curiously while saying hello. Nobody knows how he learned to say "Allo" with a French accent or why he does sometimes does it, but he decided that a simple "Hello" would not do. Knowing that cockatoos have very powerful beaks, poor Dave was more than a little nervous about Sid's intentions but Sid is a very gentle bird.
