I think this is a red naped sapsucker due to the slight red below the beak and above the beak on the forehead. Seems to have the same white pattern on the face. However, the yellowish breast is confusing me. It was in East Glacier, MT so it's possible it's a Yellow Breasted Sapsucker. Any thoughts?
Either way, he is really hard looking so I'm guessing a juvenile. Enjoy!
