A male red-shafted northern flicker (Colaptes auratus) looks out from the nest it is building in a snag in the Washington Park Arboretum, Seattle, Washington. The red-shafted northern flicker, also known as the western flicker, is a type of woodpecker and builds its nest by hollowing out decaying trees. It removes most of the wood chips to form a cavity in the tree, but reserves some wood chips to insulate and cushion its eggs.
