The Northern Flicker (Colaptes auratus) is a medium-sized member of the woodpecker family. In California we have the "Red-shafted" Flicker (the "yellow-shafted" form occurs east of the Rockies). These woodpeckers have a brown crown and gray face, the male has a red stripe, In flight, you will see red flashes under the wings and a white rump.

Northern Flickers are found in areas with tall trees around campus, such as near the administration building and along Perimeter Road.
Northern Flickers are found in a wide variety of habitats including woodlands, forest edges, and open fields with scattered trees, as well as city parks and suburbs.
Nesting Northern Flickers typically nest in cavities in dead trees or wooden posts (they may rarely nest in a ground burrow). The cavity is excavated by both sexes. The Pairs are monogamous
Feeding Flickers are often seen foraging on the ground as their preferred food is ants, but other insects and fruits and seeds are also eaten.
