Woodpeckers are fairly common in the Arboretum. The most common species are the Nuttall's Woodpecker (Picoides nuttallii) and the Northern Flicker (Colaptes auratus), although Downy Woodpecker (Picoides pubescens) and others may be seen as well. They use their chisel-like beaks to peck holes in tree bark, looking for insects to eat.
Downys are our smallest woodpecker species. They appear similar to the less common hairy woodpecker, but can be discerned by their smaller size and proportionately smaller bill. These two species can be differentiated from others by a patch of white on the back. They are often seen on the tips of smaller branches or on lighter materials such as reeds or tules, when along water.
