I’ve seen a cockatoo once who would go crazy for one of his owner’s old slippers, courting and then fucking it. The most the owner did was to buy herself a new pair of slippers, and leave the old one so the bird could have his fun.

I guess the idea of punishing him never went through her mind. Or mine, really; c’mon, birds don’t understand decorum, and the whole thing was hilarious and obviously harmless to the bird.
