Scientists have found that woodpeckers avoid getting their beaks stuck in wood by moving the top and bottom halves of their bills independently - behaving exactly like an electric drill.
Biologists at the University of Antwerp in Belgium discovered that the woodpecker gets stuck in the tree trunk and then detaches itself by flicking its head - all in the space of 50 milliseconds.
Lead researcher Sam Van Wassenbergh made videos of two birds from separate zoos which found that the creatures pecked at trees at a speed of about seven metres per second.
When the video was played in slow motion, the scientists found that the birds would rotate their heads one way, twisting the top of the beak by a few degrees and then turn the bottom half in the other direction.
