Love this, clever idea. They train crows to pick up litter and put it in a machine and they get food in exchange

It helps stop the crows eating the unsuitable rubbish and get good for them food instead
And the machine can tell the difference between stones and rubbish in case those crows get sneaky
I wonder if they could get them to do chewing gum?
One thought though, won’t this mean more crow poop everywhere?
And the comment makes you think, doesn’t it?
“Also from the perspective that we can teach crows to pick up cigarette butts but we can’t teach people not to throw them on the ground. That’s an interesting thought,”
