    I don’t have my books with me, but that looks like a Flicker? Field markings: short tail, serious beak of a woodpecker. Tannish with black cross things on the back, yellow or orangy feather shafts on wings (which should be more yellow or orangy on the undersids). Red mustache, red mark on back of the head.

    Location and orangy feather shafts would lead me to guess Northern Flicker, red-shafted form.

    I agree with Northern Flicker, but I’d actually guess this to be an intergrade male. I believe the malar stripe is only found on the males. Black in yellow-shafted, and red in red-shafted. However, the red on the nape is never present in red-shafted, only yellow, so the combination of the two leads me to think of hybridization.

    I have these fellows in my woods…but not the hybrid…just the red-shafted. They are a little shy but pretty noisy.

    I agree with Northern Flicker, and I did find a one-sentence blurb in a book that mentioned the red- and yellow-shafted morphs will hybridize, especially on the western end of their range, but saw no pictures of a hybrid. The red moustache and brown foreheadindicates a red-shafted, but the red nape says yellow (as all ready mentioned) – gotta’ be a hybrid.
