Acorn Woodpecker granary.

An Acorn Woodpecker Melanerpes formicivorus at its 'granary'. Such food storage sites can be composed of 1000s of specially drilled holes in trees or wooden utility poles, each holding one acorn or nut - although none seem to be stored at the moment in this site. Taken in the USA by Peter Basterfield.
