Hairy
Woodpecker

Thick bones and spongy cartilage fill the skull to absorb shock and protect the brain during rapid pecking and can hammer wood up to 100 times per minute without getting a headache.

Their sticky tongue is at least twice the length of their bill, used to probe deep tunnels for grubs.

Fine, stiff feathers cover their nostrils (nares) to block out flying sawdust and stiff tail feathers prop the birds up against tree trunks, supported by specialized muscles.
