I wonder what other tasks we could train species to do in exchange for something they want? For instance, cane toads are invasive and toxic enough that predators usually leave them alone. Supposing that cane toads can be deposited in a receptacle by some bird who wouldn't otherwise eat it without being harmed by the toxin, could they be used to eradicate cane toads in places where they're not wanted in exchange for food?

A fellow trained his cat to "hunt" whiffle balls around the apartment so it would have a chance to, well, act like a cat for its food. Sort of. It's neat, anyway.

Crows have 'learned' to eat toads. They just flip them and eat the stomach.
