The pied kingfisher (Ceryle rudis) is a species of water kingfisher widely distributed across Africa and Asia. Originally described by Carl Linnaeus in 1758, it has five recognised subspecies, and is the only member of the genus Ceryle. Its black and white plumage and crest, as well as its habit of hovering over clear lakes and rivers before diving for fish, make it distinctive. Males have a double band across the breast, while females have a single broken breast band. They are usually found in pairs or small family groups. When perched, they often bob their head and flick up their tail.
This is a medium-sized kingfisher, about 25 cm (9.8 in) long with a 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. The subspecies syriacus is a larger northern bird similar to the nominate subspecies (following Bergmann's rule). Subspecies leucomelanura is found from Afghanistan east into India, Thailand and Southeast Asia. The subspecies travancoreensis of the Western Ghats is darker with the white reduced. The 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.
