Large woodpecker endemic to the deep thorn forest of the Chaco of western Paraguay, SE Bolivia, and N Argentina. Similar to Lineated Woodpecker, but note all black underparts and pale auriculars on Black-bodied. From Cream-backed Woodpecker by darker bill, black back, and long drum. Calls a rising, nasal “kwee?” note given in a long repetitive series. Drum long, quick, and accelerating, but tends to be shorter than the drum of Lineated.
