SILLY QUESTIONS DEPARTMENT SPECIAL -- A: It doesn't look like it. Evolution has provided them with air bags inside their cranium,
which act like cushions, protecting their brain when the bird hammers on a tree
trunk looking for insects to eat. Also, their craniums are very light – only 1%
of their body weight – with a structure made up of lots of tiny bones, thus
distributing the impact more efficiently. My head, however, is unprotected from the Silly Questions Department: it is sometimes difficult to classify the questions you send in, but keep them coming! Please (they're fun!) (Answer from Quo Magazine)
