My cockatoo is very conscious about pooping anywhere but his cage or his play trees, and will give me a fair warning to walk him over to a place he can poop. I've never had to train him this either. He has just never pooped outside the room where his cage is, an anywhere but his cage / tree.
My cockatiel, however, poops like a machine gun. It's like one little poop after another - and SHE has no qualms about pooping on me.
