Small toucan found across southern Amazonia. Unlikely to be confused in range. Essentially dark above with entirely yellow underparts; note the bare blue skin above the eye. Named for the squiggly dark markings on the bill. Typically found in pairs or small groups in the canopy of lowland forest and edges, up into the foothills of the Andes. Often seen perched conspicuously on a snag, or foraging in a fruiting tree.
