Colaptes auratus cafer x Colaptes auratus auratus
I have seen this particular Flicker several times this winter -- the first time I saw it, I did not have my camera, but I realized it was unusual (and was not sure afterward if I really saw what I thought I did). By far the most common Flickers here are the Red-Shafted variety, where the males sport a red mustache below the eye. Yellow Shafted Northern Flickers have a black mustache and a red patch on the back of their heads. This one clearly has both markings in red! Along the Eastern Rocky Mountains, the two varieties overlap, and crossbreeding happens, producing offspring with characteristics of both subspecies.
