Seriously, they are 17 inches long! (according to the National Audubon Society Field Guide to Birds). They are called the Pileated Woodpecker and are the largest woodpecker in North America. A pair of them showed up outside the kitchen door this afternoon, assaulting our trees in their search for bugs. It was difficult to get the photographs because I used the zoom feature and their heads were really moving fast. I hope they come back! Aren't they magnificent!?
