HI Folks, Yesterday morning Daniel and I saw a flicker fly up to one of our bluebird boxes out front of our house. It had yellowish-salmon underwings, indicating an intergrade. It began drumming on the box now and then. We could see it had a red crescent on the back of the head (nape). This is one characteristic of a male yellow-shafted flicker. It also had a red "mustache," which is a character of a male red-shafted flicker. So, pretty clearly an intergrade. We often don't look closely at flickers, but the color of their head, color of marks on their head, in addition to the color of their wings in flight, can tell you a lot: whether you have a male or female, and which form of the species. Several intergrades have been reported in eBird this winter. I think if we looked more often we would find them more frequently. I thought I would show some photos of this one. Photos are through the thick fog, but I think you can see the marks on the head. https://www.flickr.com/photos/matthewghunter/sets/72157649851223437/ Matt
