Acorn Woodpeckers are distinctive birds for many reasons. Not only do they feature a striking color pattern, their social life and foraging behaviors are fascinating. Unlike most birds, these live in complex family groups with soap operatic interactions. Several different individuals of each sex may breed within one family, with everyone pitching in to care for eggs and young. All members of a group spend large amounts of time storing acorns in trees. Favorite storage trees may have up to 50,000 holes, each of which is filled with an acorn. Acorn Woodpeckers live year-round in oak and pine-oak woodlands of western CA, southern AZ and NM, and south through Mexico and Central America.
