Acorn Woodpecker: Melanerpes formicivorus   7 comments

These social woodpeckers spend their days jamming acorns into the holes they drill. As acorns dry and shrink, they’ll move them into smaller holes. The maintenance of their stores takes a lot of their time … so they generally work cooperatively. They live in groups, and always keep a guard around their acorn horde to ensure no interlopers, such as a stellar jay, steals the nuts they have stored. Acorn woodpeckers have been found living in groups with as many as 7 breeding males, 3 breeding females and 10 non-breeding helpers. The group makes a single nest, and young are raised by the community.
