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 or Alcedinidae are a family of small to medium-sized, brightly colored birds in the order Coraciiformes. They have a cosmopolitan distribution, with most species found in the tropical regions of Africa, Asia, and Oceania but also can be seen in Europe. They can be found in deep forests near calm ponds and small rivers. The family contains 114 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. They consume a wide range of prey usually caught by swooping down from a perch. While kingfishers are usually thought to live near rivers and eat fish, many species live away from water and eat small invertebrates. Like other members of their order, they nest in cavities, usually tunnels dug into the natural or artificial banks in the ground. Some kingfishers nest in arboreal termite nests. A few species, principally insular forms, are threatened with extinction. In Britain, the word "kingfisher" normally refers to the common kingfisher.
The belted kingfisher is a large, conspicuous water kingfisher, native to North America. All kingfishers were formerly placed in one family, Alcedinidae, but 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 gorget that is often broken in the middle. 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 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 resident breeding bird which occurs from southern Texas in the United States south through Central and South America to central Argentina.
The lilac-breasted roller is an African bird of the roller family, Coraciidae. It is widely distributed in sub-Saharan 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 conspicuously at the tops of trees, poles or other high vantage points from where it can spot insects, lizards, scorpions, snails, small birds and rodents 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 are different 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.
Megaceryle is a genus of very large kingfishers. They have a wide distribution in the Americas, Africa and southeast Asia.
The Amazon kingfisher is a resident breeding kingfisher in the lowlands of the American tropics from southern Mexico south through Central America to northern Argentina.
The American pygmy kingfisher is a resident breeding kingfisher which occurs in the American tropics from southern Mexico south through Central America to western Ecuador, and then around the northern Andes cordillera in the east to central Bolivia and central Brazil. The species occupies the entire Amazon basin and the Tocantins River drainage adjacent in Pará state Brazil. 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, stretching eastwards from the Indian Subcontinent towards Japan. It forms a species complex with the other three Megaceryle species.
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 purple roller, or rufous-crowned roller, is a medium-sized bird widespread in sub-Saharan Africa. Compared with other rollers its colours are rather dull and its voice rather harsh and grating.
The green-and-rufous kingfisher is a resident breeding bird in the lowlands of the American tropics from southeastern Nicaragua south to southern Brazil.
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.
The brown-hooded kingfisher is a species of bird in the subfamily Halcyoninae, the tree kingfishers. It has a brown head and blackish and turquoise wings. It is found in Sub-Saharan Africa, living in woodland, scrubland, forest edges, and also suburban areas. The International Union for Conservation of Nature (IUCN) has assessed it as being of least concern.
Ispidina is a genus of small insectivorous African river kingfishers.
Corythornis is a genus of small African river kingfishers.
