The giant kingfisher (Megaceryle maxima) is the largest kingfisher in Africa, where it is a resident breeding bird over most of the continent south of the Sahara Desert, other than the arid southwest.
The first formal description of the giant kingfisher was by the German naturalist Peter Simon Pallas in 1769 under the binomial name Alcedo maxima. [2] The current genus Megaceryle was erected by the German naturalist Johann Jakob Kaup in 1848. [3]
There are two subspecies: [4]
The nominate subspecies M. m. maxima occurs in wooded savanna while M. m. gigantea prefers tropical rainforest. [5]
The giant kingfisher is 42–46 cm (16.5–18 in) long, with a large shaggy crest, a large black bill and fine white spots on black upperparts. The male has a chestnut breast band and otherwise white underparts with dark flank barring. The female has a white-spotted black breast band and a chestnut belly. [5] The forest race M. m. gigantea is darker, less spotted above, and more barred below than the nominate race, but the two forms intergrade along the forest edge zone. [5]
The call is a loud wak wak wak.
In South Africa breeding takes place between September and January, in Zimbabwe from August to March, in Zambia March to April and in Liberia December to January. [5]
The giant kingfisher is monogamous and a solitary breeder. The nest is a long horizontal tunnel that is excavated into a river bank by both sexes using their feet and bills. The entrance hole is 11 cm (4.3 in) high and 15 cm (5.9 in) wide. The tunnel is typically 2 m (6 ft 7 in) in length but a tunnel of 8.5 m (28 ft) has been recorded. A clutch of around three eggs is laid in a chamber at the end of the tunnel. [5]
This large species feeds on crabs, fish, and frogs, caught by diving from a perch.
Kingfishers are a family, the Alcedinidae, of small to medium-sized, brightly coloured birds in the order Coraciiformes. They have a cosmopolitan distribution, with most species living in the tropical regions of Africa, Asia, and Oceania, but also can be found in Europe and the Americas. They can be found in deep forests near calm ponds and small rivers. The family contains 118 species and is divided into three subfamilies and 19 genera. All kingfishers have large heads, long, sharp, pointed bills, short legs, and stubby tails. Most species have bright plumage with only small differences between the sexes. Most species are tropical in distribution, and a slight majority are found only in forests.
The belted kingfisher is a large, conspicuous water kingfisher, native to North America. All kingfishers are placed in one family, Alcedinidae, and recent research suggests that this should be divided into three subfamilies.
The pied kingfisher 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.
The great spotted cuckoo is a member of the cuckoo order of birds, the Cuculiformes, which also includes the roadrunners, the anis and the coucals.
The blue-bellied roller is a member of the roller family of birds which breeds across Africa in a narrow belt from Senegal to northeast Democratic Republic of the Congo. It is resident, apart from some local seasonal movements, in mature moist savannah dominated by Isoberlinia trees.
The malachite kingfisher is a river kingfisher which is widely distributed in Africa south of the Sahara. It is largely resident except for seasonal climate-related movements.
The white-throated kingfisher also known as the white-breasted kingfisher is a tree kingfisher, widely distributed in Asia from the Sinai east through the Indian subcontinent to China and Indonesia. This kingfisher is a resident over much of its range, although some populations may make short distance movements. It can often be found well away from water where it feeds on a wide range of prey that includes small reptiles, amphibians, crabs, small rodents and even birds. During the breeding season they call loudly in the mornings from prominent perches including the tops of buildings in urban areas or on wires.
The green kingfisher is a species of "water kingfisher" in the subfamily Cerylinae of the family Alcedinidae. It is found from southern Texas in the United States south through Central America, in every mainland South American country except Chile and Trinidad and Tobago.
The lilac-breasted roller is an African bird of the roller family, Coraciidae. It is widely distributed in Southern and Eastern Africa, and is a vagrant to the southern Arabian Peninsula. It prefers open woodland and savanna, and it is for the most part absent from treeless places. Usually found alone or in pairs, it perches at the tops of trees, poles or other high vantage points from where it can spot insects, amphibians and small birds moving about on the ground. Nesting takes place in a natural hole in a tree where a clutch of 2–4 eggs are laid, and incubated by both parents, who are extremely aggressive in defence of their nest, taking on raptors and other birds. During the breeding season the male will rise to a fair height, descending in swoops and dives, while uttering harsh, discordant cries. The sexes do not differ in coloration, and juveniles lack the long tail streamers of adults. This species is unofficially considered the national bird of Kenya. Alternative names for the lilac-breasted roller include the fork-tailed roller, lilac-throated roller and Mosilikatze's roller.
The American green kingfishers are the kingfisher genus Chloroceryle, which are native to tropical Central and South America, with one species extending north to south Texas.
Megaceryle is a genus of very large kingfishers. They have a wide distribution in the Americas, Africa, and Southeast Asia.
The American pygmy kingfisher is a species of "water kingfisher" in subfamily Cerylinae of family Alcedinidae. It is found in the American tropics from southern Mexico south through Central America into every mainland South American country except Chile and Uruguay. It also occurs on Trinidad.
The African pygmy kingfisher is a small insectivorous kingfisher found in the Afrotropics, mostly in woodland habitats.
The crested kingfisher is a very large kingfisher that is native to parts of southern Asia. It is part of the kingfisher genus (Megaceryle) with three other species: the giant kingfisher, the ringed kingfisher, and the belted kingfisher with which it forms a species complex.
The ringed kingfisher is a large, conspicuous, and noisy kingfisher bird commonly found along the lower Rio Grande Valley in southeasternmost Texas in the United States through Central America to Tierra del Fuego in South America.
The buff-breasted paradise kingfisher is a bird in the tree kingfisher subfamily, Halcyoninae. It is native to Australia and New Guinea. It migrates in November from New Guinea to its breeding grounds in the rainforest of North Queensland, Australia. Like all paradise kingfishers, this bird has colourful plumage with a red bill, buff breast and distinctive long tail streamers.
The grey-headed kingfisher is a species of kingfisher that has a wide distribution from the Cape Verde Islands off the north-west coast of Africa to Mauritania, Senegal and Gambia, east to Ethiopia, Somalia and southern Arabia and south to South Africa.
The green-and-rufous kingfisher is a species of "water kingfisher" in subfamily Cerylinae of family Alcedinidae. It is found in the American tropics from Nicaragua to Panama and in every mainland South American country except Argentina, Chile, and Uruguay.
The Philippine dwarf kingfisher is a species of bird in the family Alcedinidae that is endemic to the Philippines found in the islands of Luzon, Polillo Islands, Catanduanes, Basilan, Samar, Leyte and Mindanao. Its natural habitat is tropical moist lowland forests. It is threatened by habitat loss.
Ispidina is a genus of small insectivorous African river kingfishers.
