This flashy woodpecker is a ground feeder (likes ants) and is easily identified by the bright flashes of red in its wing shafts when in flight and also by its distinctive call (kleeyah!). First time I ever saw one of these guys was on a trail at Spooner Lake on the Nevada side of Tahoe. I am so jazzed that they are also common here on the property.
There are two distinct forms of this Flicker: the Red-Shafted is found in the West, while the Yellow-Shafted is found in the Northern & Eastern parts of North America. There are intermediates of both forms since they are known to interbreed freely.
