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. 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.
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 the crested kingfisher (Megaceryle lugubris).
The pied kingfisher is estimated to be one of the three most numerous kingfishers in the world; the other two are the common kingfisher and collared kingfisher. It is a noisy bird, making it hard to miss.
When perched the pied kingfisher often bobs its heads up and down and will sometimes raise its tail and flick it downwards. It calls often with sharp chirruk chirruk notes. Unlike some kingfishers, it is quite gregarious, and forms large roosts at night.
