Watching the woodpecker, I am amazed at how fast it tears the bark of the tree. Indeed, in order to earn their living, the woodpecker have to make 20 to 50 beats per second. When a load from woodpeckers does not happen no concussion, no headaches. According to scientists, this is not happening due to the fact that the skull and beak of the bird move strictly in a straight line without making rotational movements, which turned the bird's neck.
His strong beak woodpeckers hollow out cavities, extract insects from the bark, and in the winter the seeds from cones. And even strokes with the beak of the woodpecker produces not only for getting pimp, but also to attract females and warn the opponent about their views on it.
