Acorn Woodpecker: Year-round resident from southern Oregon south through California, and in Arizona, New Mexico, and western Texas; also found in the tropics. Preferred habitats include open oak and pine-oak forests.
Breeding and Nesting
Acorn Woodpecker: Three to seven white eggs are laid in a hole in a tree. Incubation ranges from 11 to 14 days and is carried out by both parents. Usually nests in colonies with all members sharing in excavation of holes, mostly in dead oak branches.
Foraging and Feeding
Acorn Woodpecker: Primary diet consists of insects, sap, oak catkins, fruits, and flower nectar; acorns are critical for winter survival. Occasionally eats grass seeds, lizards, and bird eggs. Most foraging is performed in or near the canopy; rarely goes to the ground except to pick up grit and fallen acorns.
