Breeding Behavior
In California, Acorn Woodpeckers breed from May–July. An Acorn Woodpecker group may consist of 1–7 male breeders that compete to mate with 1–3 females. The nest is excavated in a large tree, which may also be a granary tree. Tree cavities are created in both dead and living trees and snags and nest holes are reused for many years. Females typically lay 5 eggs that are incubated for 11–14 days. Male and females incubate and tend to their young. Non-breeding helpers (young from previous years) often help with incubation and other parental duties. The young leave the nest and take their first flight at approximately 30–32 days after hatching and return to the nest to be fed for several weeks.

Famous quotes containing the words breeding and/or behavior:
“The test of a man’s or woman’s breeding is how they behave in a quarrel. Anybody can behave well when things are going smoothly.”
—George Bernard Shaw (1856–1950)
“The ease with which problems are understood and solved on paper, in books and magazine articles, is never matched by the reality of the mother’s experience. . . . Her child’s behavior often does not follow the storybook version. Her own feelings don’t match the way she has been told she ought to feel. . . . There is something wrong with either her child or her, she thinks. Either way, she accepts the blame and guilt.”
—Elaine Heffner (20th century)
