Megaceryle is a genus of very large kingfishers. Megaceryle is from the Ancient Greek megas, "great", and the existing genus Ceryle. It comprises four species: * Giant kingfisher, Megaceryle maxima * Crested kingfisher, Megaceryle lugubris * Belted kingfisher, Megaceryle alcyon * Ringed kingfisher, Megaceryle torquata These birds nest in horizontal tunnels made in a river bank or sand bank. Both parents excavate the tunnel, incubate the eggs and feed the young.
