Not sure why this is called a "Hairy" Woodpecker, but I love his red hat. The pecked wood is pretty cool also. For some reason, Woody Woodpecker just came to mind and especially the annoying cartoon jingle. It's amazing what useless stuff still lives in my brain.
Correction: This just in. According to my mom, this is an Acorn Woodpecker. I think she's right. It has a "conspicuous white rump" (from Peterson).
