16-410: 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
32-402: 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
48-457: A perch, often manipulating the subject with its bill and swallowing in flight, and so can hunt over large water bodies or in estuaries that lack perches required by other kingfishers. The breeding season in India is February to April. Its nest is a hole excavated in a vertical mud bank about five feet above water. The nest tunnel is four to five feet deep and ends in a chamber. Several birds may nest in
64-473: 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 the crested kingfisher ( Megaceryle lugubris ). The pied kingfisher is estimated to be one of
80-474: 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. The pied kingfisher was one of the many bird species originally described by Linnaeus in the landmark 1758 10th edition of his Systema Naturae , who noted that it lived in Persia and Egypt. He named it Alcedo rudis . The German naturalist Friedrich Boie erected
96-614: The cerylid kingfishers . All six American species are in this subfamily. These are all specialist fish-eating species, unlike many representatives of the other two subfamilies, and it is likely that they are all descended from fish-eating kingfishers which founded populations in the New World . It was believed that the entire group evolved in the Americas, but this seems not to be true. The original ancestor possibly evolved in Africa – at any rate in
112-675: The Old World – and the Chloroceryle species are the youngest ones. Evidence from molecular phylogenetic studies suggests that the Cerylinae originated in Asia and have colonised the New World on two occasions: the first time was around 8 million years ago by the Chloroceryle and the second time was around 1.9 million years ago by the common ancestor of the ringed kingfisher and the belted kingfisher in
128-458: The flesh of pied kingfishers. This led to a comparative study of edibility of birds and he suggested that more conspicuously plumaged birds may be less palatable. This suggestion was, however, not supported by a subsequent reanalysis of his data. [REDACTED] Water kingfisher Megaceryle Ceryle Chloroceryle The water kingfishers or Cerylinae are one of the three subfamilies of kingfishers , and are also known as
144-434: The genus Megaceryle . The subfamily Cerylinae contains nine kingfisher species and is divided into three genera: Protocalliphora Protocalliphora or bird blowflies are a blow fly genus containing many species which are obligate parasites of birds. Eggs are laid in bird nests. After hatching, the larvae suck the blood of nestlings. They sometimes feed inside the nostrils of nestling birds and destroy
160-436: The genus Ceryle in 1828. The name is from classical Greek kērulos , an unidentified and probably mythical bird mentioned by Aristotle and other authors. The specific epithet rudis is Latin for "wild" or "rude". The pied kingfisher is the only member of the genus Ceryle . Molecular analysis shows it is an early offshoot of the lineage that gave rise to American kingfishers of the genus Chloroceryle . The pied kingfisher
176-511: 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

#1732880979581192-536: The same vicinity. The usual clutch is three to six white eggs. The pied kingfisher sometimes reproduces cooperatively, with young non-breeding birds from an earlier brood assisting parents or even unrelated older birds. In India, nestlings have been found to be prone to maggot infestations (probably by Protocalliphora sp.) and in some areas to leeches. Nest holes may sometimes be used for roosting. In 1947, British zoologist Hugh B. Cott noticed while skinning birds that hornets were attracted to certain birds but avoided
208-585: 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. This kingfisher feeds mainly on fish, although it will take crustaceans and large aquatic insects such as dragonfly larvae. It usually hunts by hovering over
224-485: The tissue at the base leading to reduced growth of the upper mandible and the young growing with "shovel-beaks". The species overwinter as adults. The genus is affected by Wolbachia bacteria and it has been suggested that horizontal gene transfer may have led to the difficulty in separating species of Protocalliphora through DNA barcoding , with several species possessing identical mtDNA Cytochrome oxidase I sequences.

240-517: The water to detect prey, before diving vertically bill-first to capture fish. When not foraging, it has a straight rapid flight and have been observed flying at speeds approaching 50 km/h. In Lake Victoria in East Africa, the introduction of the Nile perch reduced the availability of haplochromine cichlids which were formerly the preferred prey of these birds. It can consume prey without returning to
256-507: Was initially believed to be descended from an ancestral American green kingfisher which crossed the Atlantic Ocean about one million years ago. A more recent suggestion is that the pied kingfisher and the American green kingfishers are derived from an Old World species, with the pied kingfisher or its ancestor losing the metallic colouration afterwards. There are five subspecies : This is
