The head woodpecker pecking a tree, being overloaded, 1,000 times the acceleration due to gravity

The head woodpecker pecking a tree, with each stroke is moving at a speed of 6 meters per second, while being exposed to a huge overload. Why had not damaged the brain?
Scientists have long studied the anatomy of the skull woodpeckers, trying to understand how they manage so hard knock on wood, without causing yourself any harm in this. It was found that the brains of these birds tight to the skull, and therefore he is physically no room for movement. Furthermore, the brain woodpecker large elongated vertical than horizontal, and thus, the load is distributed over a larger area.

Hyoid loop extending around the entire skull bird acts as a kind of belt, especially in the first moments after hitting its beak. The length of the upper and lower parts of the bird's beak is different, and this asymmetry as the transmission of force from the tip of the beak to the bone reduces the load on the brain. Finally, the experts found that the uniform distribution of the load and, as a result, the brain also contribute to the protection plate to cancellous bone structure in the different parts of the skull.

The brain of woodpeckers is protected from damage due to the combination of all these factors, rather than any one single feature.
