Crimson-crested Woodpecker Campephilus melanoleucos

Large red-headed woodpecker, widespread from Panama to Paraguay. Found in lowland forest and edges, often perched conspicuously high up on a snag or large tree. More apt to be seen in open habitats compared with Red-necked Woodpecker, but significant overlap. Male is distinctive with barred underparts and almost entirely red head with a black-and-white patch on the cheek. Female distinguished from other large woodpeckers (such as Lineated) by very broad white stripe on face and white V on back. Listen for loud knocking drum as well as various chattering noises.
