Back in 2002, the owners of a coin-operated car wash in Maryland had a hard time trying to figure out why they kept losing hundreds of dollars each week from their machines.

There was no evidence that the coin machines were being broken into, yet things just weren’t adding up.

The owners set something up to observe the machines and that’s how they discovered who was stealing the coins. It was small birds. They were getting into the machines through the coin returns and flying off with the shiny quarters.
