What's the legality on training an army of crows to collect loose change around the city for me?

ISTR a study where someone trained crows to retrieve street garbage. It stopped working because the peanuts or similar they were using to pay the crows were less valuable to them than the discarded pizzas etc they were supposed to be bringing back
