This footage shows two daredevil ducks ruining a man’s smoothly layered concrete by walking over it and leaving visible footprints after it was freshly cemented.

The images were obtained by Newsflash from Luke Bartley, who makes a living as a concrete contractor – and apparently has to chase away ducks to get his work done.

Luke showed off some of the challenges he faces at his job, by filming himself having to shoo off two careless birds that stick their feet in the cement he had layered and left to dry.

And by the time Luke comes in to save the hard work he had done, the ducks have already stepped off and gone along their way – but not before leaving some clear tracks in the damp pavement.
