Chunky olive-green barbet. The head pattern varies geographically, from uniform olive-green, to olive-green with a yellow or buff ear patch, to black with a yellow ear patch. Found in the canopy of lowland and montane forest, often in the vicinity of fruiting trees. Sometimes perches out on dead trees, though otherwise inconspicuous. Call is a repeated, wooden “chak”. Similar overall coloration, but much larger than green tinkerbirds.
