The Downy Woodpecker comes to mind today because they have a nest outside my front door, in a hole in a big old sugar maple, and the endless and almost annoying, rhythmic squeak squeak squeak of the hungry babies sounds exactly like a bad fan belt.
Found across the entire US and most of Canada, these cute little bug-eaters are far more common than the Hairy Woodpecker, its big brother, and is non-migratory.
