Friends, in the crypt there is now the answer to a question that I have been asking myself for years: How do woodpeckers avoid brain injuries when they are pecking at the trees? The answer is simple: The space between the skull bones and the brain mass is smaller than, for example, ours and the brain does not wobble around in the head when you bang your head. In addition, their brains are rather long (from top to bottom) than wide.
For years, scientists have examined the anatomy of woodpeckers' skulls to find out how they pull off their powerful pecking without causing themselves harm.
The birds have little "sub-dural space" between their brains and their skulls, so the brain does not have room to bump around as it does in humans. Also, their brains are longer top-to-bottom than front-to-back, meaning the force against the skull is spread over a larger brain area.
A highly-developed bone called the hyoid - which in humans is just above the “Adam's apple” - has also been studied: starting at the underside of the birds' beaks, it makes a full loop through their nostrils, under and around the back of their skulls, over the top and meeting again before the forehead.
