Northern Flicker is a rather large woopecker who nests primarily in dead trees or large branches. They forage mostly on the ground looking for ants and other nutritious insects which they lap up with their long tounges; they rarely visit seed feeders. In the winter they supplement their diet with berries and seeds. Northern Flicker has a black crescent on the neck front, a little slap of red on the neck back, shafts of yellow on the tail feathers ("Yellow-Shafted Flicker is usually the ones we see in Waldo as opposed to "red-Shafted) and great polka-dots on it's chest and belly. Much of their peck-banding occurs on metal surfaces as it is a clear and loud form of communication.
