.....okay, call me crazy.
But how possible would it be to train crows to do this in exchange for food? We know they can be trained, we know they understand transactions, and we know they can complete tasks.
That seems like at least in some places it could be desirable.
Fun fact! We've done that before. The problem is that the birds, if there was no immediate trash available, started stealing papers, wrappers, and plastic water bottles directly from people's hands. While they were still in use.
Its likely that this particular parrot is doing typical mimicry behavior. He sees people throw plastic water bottles in this spot, so he does the same. The best way to influence birds to do this, is to do it ourselves.
