They love to drop things on you from the trees. They laugh and laugh, the cacophony of screeches can be deafening. They mess with traffic all day long too, swooping cars from the traffic lights.

My family has a rescue Galah, very similar to Sulfur Crested Cockatoos and he is very smart. He knows the right words to use and when, he thinks the cat is called "ps ps ps" so he calls for the cat with ps ps ps, when it passes by. Knows how to say hello/goodnight etc and when. He also knows he can trick some people by looking away when you give him food, so you get closer, then he bites.

His wing was broken as a baby after getting stuck in a thorny bush, that's how we came to have him in case anyone is curious. He can't fly.
