    The Pied Kingfisher is a water kingfisher and is found widely distributed across Africa and Asia. Their black and white plumage, crest and the habit of hovering over clear lakes and rivers before diving for fish makes it distinctive.

    This kingfisher is about 17 cm long and is white with a black mask, a white supercilium and black breast bands. The crest is neat and the upperparts are barred in black. Several subspecies are recognized within the broad distribution. The nominate race is found in sub-Saharan Africa, extending into West Asia.

    A former subspecies syriaca is considered as merely a larger northern bird of the nominate species. Subspecies leucomelanura is found from Afghanistan east into India, Sri Lanka, Thailand and Laos. The subspecies travancoreensis of the Western Ghats is darker with the white reduced. Subspecies C. r. insignis is found in Hainan and southeastern China and has a much larger bill. Males have a narrow second breast-band while females have a single broken breast band.

    It is common throughout sub-Saharan Africa and southern Asia from Turkey to India to China. It is resident, and most birds do not migrate, other than short-distance seasonal movements. In India it is distributed mainly on the plains and is replaced in the higher hills of the Himalayas by Megaceryle lugubris. The Pied Kingfisher is estimated to be the world's third most common kingfisher, and is a noisy bird, unmissable within its range.

    It usually hunts by hovering over the water to detect prey and diving vertically down bill-first to capture fish. When not foraging, they have a straight rapid flight and have been observed flying at nearly 32 mph.

    The breeding season is February to April. Its nest is a hole excavated in a vertical mud bank about five feet above water. The nest tunnel is 4 to 5 feet deep and ends in a chamber. Several birds may nest in the same vicinity. The usual clutch is 3-6 white eggs.
