The Northern Flicker is a combination of what once was thought of as three separate species of birds: Yellow-shafted Flicker, Red-shafted Flicker and Gilded Flicker. When it was realized these groups actually consisted of one interbreeding population they were reclassified as the Northern Flicker, one of the most unusual woodpeckers as it feeds on the ground. Northern Flickers are found year-round in most of the United States except southern Texas where you will only see them in the winter months. Enjoys feeding on Black Oil Sunflower, Sunflower Hearts, Cracked Corn, Nuts.
