Acorn Woodpeckers (Melanerpes formicivorus) are larder hoarders. Breeding groups create a granary by drilling holes in a dead tree,and stuffing acorns into them. The acorns are visible,and the group defends the tree against potential cache robbers. The acorns represent a significant part of their diet; they also eat insects,fruit,seeds and sometimes tree sap.
