The black-bodied woodpecker (Dryocopus schulzii) is a Near Threatened species of bird in subfamily Picinae of the woodpecker family Picidae. It is found in Argentina, Bolivia, and Paraguay. The black-bodied woodpecker is 29 to 30 cm (11 to 12 in) long. Both sexes have a long pointed crest. Adult males have a red forehead and crest. They have gray ear coverts, a very thin and short white stripe behind the eye, a white stripe from the lores to under the ear coverts and continuing down the side of the neck, a red malar stripe with a bit of black at its back end, and a white chin. Adult females have a black malar stripe and a blackish lower forehead but are otherwise the same as males. Adults of both sexes have a black throat and hindneck and are mostly black below the neck. The southern population has black scapulars; those of the northern population have white on the scapulars' outer webs that continues the white neck line. Their flight feathers are black with white bases. The upper side of their tail is black with white feather shafts; the underside is black to brownish black. Their flanks and lower belly often have some faint yellowish barring. Their bill is a long pale ivory-white chisel with a darker culmen and base, their iris deep brown to red-brown, and their legs dark gray. Juveniles are duller and browner than adults and with more barring on the flank.
