I heard this woodpecker making quite a racket, so I headed out to investigate.  I finally found him, but it was difficult to get close enough to get a good picture.

The nuttals and the ladder-backed woodpeckers are very similar in appearance, but I think that it’s markings and bill length indicate that it is a nuttals woodpecker.  On this identification I used Whatbird.com; I’ve found it accurate and simple to use.
