comment about this bird

The speed at which the beak of a woodpecker hits the trunk of a tree is 7 m/s. And at the moment when the beak meets the tree, the bird's head experiences a blow, the force of which is 1000 times greater than the force of gravity.

However, in these birds, the space between the layers of dense bone matter is filled with peculiar plates running parallel to the outer dense layers. Due to this, shock vibrations dissipate and weaken.
