Northern Flicker Male
The wing lining on this one doesn't look distinctly red or yellow.The Yellow-shafted Flickers and Red-shafted Flickers that breed here are considered to be subspecies of the Northern Flicker. According to "The Atlas of Breeding Birds of Alberta", the Yellow-shafted Flicker breeds in most parts of the province except in the mountain regions of the southwest where the Red-shafted Flicker occurs. Interbreeding is common with hybrids (intergrades) found to the BC border. Very few of "pure" Red-shafted Flickers are found in the province now.
The more distinct examples of the subspecies are identified by the presence of yellow under the tail and wing linings (Yellow-shafted) or red under the tail and wing linings (Red-shafted)
The male Red-shafted has a red malar and no red at the nape of the neck. Their crowns are more brown than gray. The male Yellow-shafted has a black malar (mustache) and a red crescent on the nape of the neck.
In Alberta, the subspecies interbreed so frequently that various combinations of these characteristics can occur.
I think the main shot in this posting is one such combination.
I added shots of more pure examples of each subspecies in the comment box. Both of these were posted awhile back
Northern Flicker works for all.
