Managed to get some pretty good head shots of the male Red-shafted Northern Flicker. I threw in a head shot of the male Yellow-shafted (last picture) so you could get a comparison. The red-shafted has a red mustache where as the yellow has a black one. The yellow male has red markings on the back of the head where as the red has none. You can also just see the feather shaft coloring under the tail.
