This woodpecker needs to get his eyes checked.

Landing on a member of the animal patrol unit for the city of Lodz, Poland, the woodpecker proceeded to peck and inspect the human, attempting to drill its way into the man's shoulder than then neck.

Perhaps the woodpecker required assistance from animal patrol, and this was the only way it could relay its request. Or maybe it thought the man looked like J.R.R. Tolkien's tree/man species, the Ents, and it could make itself a mobile home. Whatever the case, luckily the patrolman was game for the encounter.
