  More likely, crows could game it by breaking up litter into smaller pieces to get more credit for the same work, or going after easier pickings that don't count as litter and don't need to be removed (rocks, twigs). Example of dolphins doing the first trick: >> Kelly [the dolphin] has taken this task one step further. When people drop paper into the water she hides it under a rock at the bottom of the pool. The next time a trainer passes, she goes down to the rock and tears off a piece of paper to give to the trainer. After a fish reward, she goes back down, tears off another piece of paper, gets another fish, and so on. https://www.theguardian.com/science/2003/jul/03/research.science https://www.theguardian.com/science/2003/jul/03/research.sci...
