Acorns stored by acorn woodpecker. Close-up of acorns stored in holes bored in a tree trunk by an acorn woodpecker (Melanerpes formicivorus). These woodpeckers are native to the hills of coastal areas and foothills of California and the southwestern United States south to Colombia. They store food in special storage trees known as 'granary trees' (seen here) and other wooden structures, including manmade structures. Photographed at Mount Tamalpais, California, USA.
