Dark woodpecker, inconspicuous and uncommon. Found in coniferous forests, often in recently burned areas or bogs with many dead trees. Distinctive habit of flaking bark off trees in search of grubs; behavior shared only with American Three-toed Woodpecker. Back entirely glossy black with faint white markings only on flight feathers. Head mostly black with white mustache stripe and throat. Barred flanks. Males show yellow cap; sexes otherwise alike. "Pick" call is short and has unique clicking tone unlike other woodpeckers. Drum is slow, speeding up at end. Does not visit bird feeders.
