The Downy Woodpecker is the smallest woodpecker in North America. They are a very common site as they frequently visit bird feeders across North America. The red patch at the back of the head distinguishes this one as a male. They are also very similar superficially to the larger Hairy Woodpecker. The bigger overall size and the larger porportional bill of the Hairy are the best indicators to distinguish the two.
This little guy was taking sunflower seeds from my feeders and wedging them into this dead tree. He then pecked them open and ate the hearty inside. He returned back and forth four or five times repeating the process.
This was taken in my backyard in Cortland NY!
The scientific name of this species is: Picoides pubescens.
