On Labor Day, let’s watch some crows at work.

At a theme park in France trained crows are showing humans not to litter.  At least that’s one of the ideas behind teaching crows to pick up cigarette butts at Puy du Fou.

The historical theme park in Les Epresses, France has falconers who conduct live bird shows featuring falcons, owls, vultures and crows.  One day one of the crows picked up litter instead of the prop he was cued for.  The crowd was impressed.

Management was impressed too so now they have six trained crows who pick up cigarette butts in exchange for a treat.

The crows love their job. Their trainer says they’d do it all day if you let them.  Click here or on the image below to watch the crows in action.
