Second mystery solved ("Why don't woodpeckers give themselves serious concussions?")
Last week, I posed the question:
Why don't woodpeckers get concussions, or, at the very least, terrible headaches from bashing their faces against trees all day?I did a little research, and I found the answer:
For one thing, they tend to choose sponge-y, soft wood for drilling purposes.
For another, they slam straight into a tree in a way that maximizes impact to the wood while protecting them against head trauma (much the same way that a hammer slams a nail.)
And, finally, they have unusually strong neck muscles, which absorb most of the shock.
I'm glad no one answered this question because I ran out of prizes two weeks ago (and, as you know, the prize that I sent out has fallen apart.)
