Excellent photo by Robert, catching the long probing tongue of this male pileated, as it looks for insects in this tree near the Old Field. Pileated woodpeckers have been unusually abundant in this region this past winter, and are being seen frequently by birders and casual observers in numerous locations. Like other woodpeckers, these birds nest in tree cavities, but because of their size require a larger tree and cavity than say a downy woodpecker. One year they nested in the Arboretum, and at the end of summer the dead tree they nested in fell down. I was lucky enough to come across this early in the morning before it got cleared away and could see the very deep and long nest hole ending in a bowl-shape, they'd excavated. No nest material is used, other than what bits of 'sawdust' fall to the bottom of the nest chamber. Fortunately, the tree stayed standing long enough to allow the young to fledge.
