2.  It is no insult when you call a woodpecker thickskulled.
 New research shows that woodpeckers have a hard head
that really helps them prevent from serious brain damage.
 Woodpeckers head-pounding pecking against a tree of
telephone pole the birds head is exposed to some enormous
forces.
 They can easily slam their beaks against wood with a force
1,000 times that of gravity.
 Researchers had previously figured out that thick neck
muscles diffuse the blow.
 A third inner eyelid prevents the birds' eyeballs from
popping out.

3.  The woodpecker's brain is surrounded by
thick, plate like spongy bone.
 The woodpeckers skull is the bone that is the
most important to stopping a concussion from
happening.

4.  The woodpecker's beak does not differ much
from the lark's in strength, but it contains many
microscopic rod structures and thinner
trabecular.
 It's possible that the beak is adapted to deform
during pecking.
 It absorbs the impact rather than transferring it
too the brain.
