Downy and Hairy Woodpeckers

Just a quick pic I snapped at my parent's house in Pennsylvania. A Hairy Woodpecker is the larger bird on the left, and the smaller bird on the right is a Downy Woodpecker. As you can see, the two species are almost identical except for the size. My mom came up with an easy way to remember it though. Downys are Diminutive, and Hairys are Huge. Hope that helps you remember, and have a happy new year!
