Of New England's nine* species of woodpeckers, the Pileated Woodpecker (PIWO) is by far the largest and the only type with a bright red crest. In flight, PIWOs flash white wing-patches. Males and females are largely similar, though only the males have red foreheads and red mustache stripes.
PIWOs feed extensively on carpenter ants and routinely drill deep, rectangular excavations to uncover their prey in tree trunks. Though PIWOs are often blamed for turning healthy trees into piles of wood chips, trees are most often dead (or dying) and thoroughly infested with wood-chewing ants (or other insects) before hole creation begins.
*Northern Flicker, Yellow-bellied Sapsucker, and Downy, Hairy, Red-bellied, and Pileated Woodpecker, account for the 6 common species; American Three-toed and Black-backed Woodpecker are residents of northern boreal forests; Red-headed Woodpecker occurs annually in New England in small numbers, but is much more common to our south and west.
