The Northern Flicker name was adopted in place of Yellow-Shafted, and Red-Shafted. They were considered two seperate species at one point, but interbreeding has blurred the lines and now they are considered one. This male obviously comes from Red-Shafted stock. It's identified as a male by the red moustache. A female doesn't have this, but has a small patch of colour on the back of the neck. In my opinion, these are one of the most beautifully marked North American birds.
