Crows gather cigarette butts!

Most cities hire people to pick up cigarette butts. Sweden hired crows. And they work for peanuts. Literally. A Swedish startup called Corvid Cleaning built a machine that rewards wild crows for picking up cigarette butts — the number one litter item in Swedish cities. A crow drops a butt into the slot, a camera verifies it, and out comes a peanut. No training camps. No cages. The crows figured out the system on their own, because corvids are among the most intelligent animals on the planet. They use tools, solve puzzles, and apparently — run side hustles. The machine tracks every deposit. The counter on this one reads 124. That's 124 cigarette butts picked up by birds no one asked to help.
