Who am I?

I chased this guy (?) around yesterday, every time I got close he flew away.
This was the best I could get.
Anyone know what it is?

I believe that is a male yellow-shafted Flicker. It should have red on the back of its head. Good capture, they are difficult to get close to.

Nice catch!

Thanks HBG and Iggy. I knew someone here would know what it was.
