Woody the Woodpecker. He is a beloved character with a Wikipedia article miles long. The reason I am bringing him up is because Wikipedia says that he is an "anthropomorphic acorn woodpecker." I completely disagree with this claim. Any person with eyes will tell you that the two simply do not match, no matter how anthropomorphous Woody gets.
This is an Acorn Woodpecker.
This is a Red-headed Woodpecker, and what I believe Woody should be classified as an anthropomorphized version of. I am basing this entirely on the head. Truthfully Woody doesn't look like any species of woodpecker I've ever seen.
