Acorn Woodpecker

This obvious clown-faced woodpecker of american oak woods is amazing for its social routines, existing over much of its vary in public categories of up to 4 or more reproduction men and as many as 3 reproduction females. These categories maintain and protect amazing granaries in which thousands of acorns are kept in gaps drilled in shrub trunks or utility posts for future consumption; in a study a single shrub included more than 50,000 acorn-storage gaps. Acorn woodpeckers also feast by sallying for traveling by air bugs and harvesting trunks, and they often eat bugs (as demonstrated in the species’ medical name). Polytypic. Length 9" (23 cm).

Separated reproduction numbers are discovered on the eastern side of the Sierra The state of nevada, California; on the central Edwards Level, Texas; and possibly in far lower Co. Vagrant: discovered seldom or satisfied, mainly in fall and winter, away from do environments along the immediate Hawaiian seacoast and in american deserts; random lower to English The philipines and eastern to the Great Flatlands states from Northern Dakota lower to seaside Tx.

Population Constant, apart from some local diminishes as a result of deterioration of oak woods.
