Merops is a genus of bee-eaters in the Meropidae family. The members of this Old World family are characterised by richly coloured plumage, slender bodies and usually elongated central tail feathers. They predominantly eat insects, especially bees, wasps and hornets, which are caught in the air. All bee-eaters are in the genus Merops and subfamily Meropinae except for three Asiatic bearded bee-eaters in the subfamily Nyctyornithinae (in genera Nyctyornis and Meropogon).
