They also feed on insects, sap, and fruit. As acorns dry out, they are moved to smaller holes and granary maintenance requires a significant amount of the bird's time. The woodpeckers then collect acorns and find a hole that is just the right size for the acorn. In some parts of their range (e.g., California), the woodpeckers create granaries or "acorn trees" by drilling holes in dead trees, dead branches, telephone poles and wooden buildings. Food and homesĪcorn woodpeckers, as their name implies, depend heavily on acorns for food. Young have been found with multiple paternity.

A group of adults may participate in nesting activities: Field studies have shown that breeding groups range from monogamous pairs to breeding collectives of seven males and three females, plus up to 10 nonbreeding helpers. The breeding pair excavate a nest in a large cavity in a dead tree or a dead part of a tree. This species may occur at low elevations in the north of its range, but rarely below 1000m in Central America, and it breeds up to the timberline. The breeding habitat is forested areas with oaks in the hills of coastal areas and foothills of California and the southwestern United States south to Colombia. Acorn woodpeckers have a call that is almost like they are laughing. The white neck, throat and forehead patches are distinctive identifiers.When flying,they take a few flaps of their wings and drop a foot or so.You can see white circles on the wings while flying. The adult male has a red cap starting at the forehead, whereas females have a black area between the forehead and the cap. The eyes are white.There is a small part on the small of their backs were there are some green feathers. The adult Acorn Woodpecker has a brownish-black head, back, wings and tail, white forehead, throat, belly and rump.
