Do You Know This Bird?

Can you find the bird on the tree?  It's right below the knot on the left aspen.  The knot looks a bit like an eye.  It's a woodpecker.  At first its head was in a hole. 

I was looking for a mountain bluebird, but they eluded my camera today.  I thought I saw a couple of them in flight.

Here is a crow in the horse pasture.  And below is a robin.
