Large gray cuckoo with green-glossed wings and red skin around the eye. Broad white tips to tail feathers visible from below. Averages paler and with darker red on the facial skin than similar Chestnut-bellied Malkoha and lacks its dark chestnut belly. Green-billed Malkoha paler gray and has bright white lines around the facial patch. Clambers about rather clumsily in trees as it forages in lowland and foothill forests. Gives a rather hollow, clipped-off hoot, as well as a bright, rising call.
