The Downy Woodpecker Picoides pubescens looks much like the larger Hairy Woodpecker Picoides villosus, but there are some differences between them. The Downy is very friendly at the feeder while the Hairy is very skittish. The Downy’s outer tail feathers are barred with black, unlike the Hairy Woodpecker’s, which are all white. The Downy has a squeakier voice while the Hairy's is more powerful. The Downy is about half the size of a Hairy and the Downy’s bill is shorter than its head, whereas the Hairy’s bill is as long its head. The Downy’s name refers to the soft white feathers of the white strip on the lower back, which differ from the more hairlike feathers on the Hairy Woodpecker.
