have to agree that cockatoos are great pets, but you really have to spend a LOT of time with them. if they get bored or stressed they can become noisy, destructive, aggressive and worse feather plucking. I used to have 4 galahs three that could not fly (wild birds with incurable injuries) and a fourth one that we kept her wing clipped. The four of them used to raom around the yard together and our neighbours never realised we even had 1 let alone 4. Some cockatoos like the Umberalla cockatoo (similar to the one in the vid) are renound for the males killing the hens.

and then gave Kalang his time out treatment of having a bucket put over him. You would hear all sorts of angry language coming out from the bucket but once he had settled down and changed his mind set, you could let him back out and he would be all lovey dovey again. kalang once took a chunk out of my bottom lip, so I think getting your feet bitten by him was tame.

with their red eyes and they can be down right evil but they are also hilarious
