This video shows a ferry boat tied up at a dock on the River Dart in Devon, UK. A bag of 20 £1 coins sat inside a metal box. This was part of the day's earnings for the ferry. Security camera footage shows that a seagull landed on the boat, slipped his beak inside the box, and flew away with the bag of money.
This isn't the bird's first foray into a life of crime. He's previously been caught stealing a newspaper.
