Cockatoo as Cock-stopper

Cockatoos need good handling. George's companion Bess's hand is wrapped in cloth for a spontaneous wing display. Bess says that George is a real "cock stopper", and gets vocal when an interested man gets too close. Last time, he threw a steak knife while squarking "Get F---ed". 
George is a Sulphur-crested Cockatoo, living at the Friend in Hand hotel in Glebe, Sydney.
The hotel has a weekly event racing hermit crabs, and is well know for poetry readings, as well as for George.
