The half-collared kingfisher (Alcedo semitorquata) is a kingfisher in the subfamily Alcedininae that is found in southern and eastern Africa. It feeds almost exclusively on fish and frequents streams, rivers and larger bodies of water with dense shoreline vegetation. [2]
The half-collared kingfisher was described by the English ornithologist William John Swainson in 1823 and given its current binomial name Alcedo semitorquata. [3] The word Alcedo is the Latin for a "kingfisher". The specific epithet semitorquata is from the Latin semi- for "half" or "small" and torquatus for "collared". [4] The blue-eared kingfisher is one of seven species in the genus Alcedo and is most closely related to the shining-blue kingfisher (Alcedo quadribrachys). [5] [6]
It is known to sometimes vocalize while approaching its nest, but the purpose or advantage of this behavior is unclear. [7]
The half-collared kingfisher is a medium-sized kingfisher. It is around 18 cm (7.1 in) in length with a weight of 35–40 g (1.2–1.4 oz). It has blue upperparts, a white throat and pale orange underparts. The head has alternating light blue and dark blue bands running across the crown and each side of the neck has a creamy white stripe. The dark blue patches on either side of the neck form a half collar. The legs and feet are red. The sexes are very similar but the bill of the male is entirely black while the female has some red at the base of the lower mandible. [2]
The common kingfisher, also known as the Eurasian kingfisher and river kingfisher, is a small kingfisher with seven subspecies recognized within its wide distribution across Eurasia and North Africa. It is resident in much of its range, but migrates from areas where rivers freeze in winter.
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 black-capped kingfisher is a tree kingfisher which is widely distributed in tropical Asia from India east to China, Korea and Southeast Asia. This most northerly of the tree kingfishers is resident over much of its range, but northern populations are migratory, wintering south of their range in Sri Lanka, Thailand, Borneo and Java. It is distinctive in having a black cap that contrasts with the whitish throat, purple-blue wings and the coral red bill. The species is mainly found in coastal and mangrove habitats but can sometimes be found far inland.
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 woodland kingfisher is a tree kingfisher that is widely distributed in Africa south of the Sahara.
The stork-billed kingfisher, is a tree kingfisher which is widely but sparsely distributed in the tropical Indian subcontinent and Southeast Asia, from India to Indonesia. This kingfisher is resident throughout its range.
The giant kingfisher 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 blue-eared kingfisher is found in Asia, ranging across the Indian subcontinent and Southeast Asia. It is found mainly in dense shaded forests where it hunts in small streams. It is darker crowned, with darker rufous underparts and lacking the rufous ear stripe of the common kingfisher which is found in more open habitats. A number of subspecies have been described that differ in measurement and colour shade. Adult males have an all dark bill while females have a reddish lower mandible.
The collared kingfisher is a medium-sized kingfisher belonging to the subfamily Halcyoninae, the tree kingfishers. It is also known as the white-collared kingfisher, black-masked kingfisher or mangrove kingfisher. It has a wide range extending from the Red Sea across southern Asia to Polynesia. A number of subspecies and subspecies groups have been split from this species including the Pacific kingfisher, the islet kingfisher, the Torresian kingfisher, the Mariana kingfisher, and the Melanesian kingfisher.
The cerulean kingfisher is a kingfisher in the subfamily Alcedininae which is native to parts of Indonesia. With an overall metallic blue impression, it is very similar to the common kingfisher, but it is white underneath instead of orange. Males average bluer than females, which have a greenish cast.
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 banded kingfisher is a tree kingfisher found in lowland tropical forests of southeast Asia. It is the only member of the genus Lacedo. Male and female adults are very different in plumage. The male has a bright blue crown with black and blue banding on the back. The female has rufous and black banding on the head and upperparts.
Alcedo is a genus of birds in the kingfisher subfamily Alcedininae. The genus was introduced by Carl Linnaeus in 1758 in the 10th edition of his Systema Naturae. The type species is the common kingfisher. Alcedo is the Latin for "kingfisher".
The little kingfisher is a species of kingfisher in the subfamily Alcedininae.
The shining-blue kingfisher is a species of bird in the family Alcedinidae. It is found in Equatorial Africa.
The Malagasy kingfisher or Madagascar kingfisher is a species of bird in the family Alcedinidae that is found in Madagascar, Mayotte and the Comoros. Its natural habitat is subtropical or tropical mangrove forests.
The chattering kingfisher is a species of bird in the kingfisher family Alcedinidae. The species is found in the Cook Islands and the Society Islands in French Polynesia.
The Society kingfisher or Tahiti kingfisher is a species of bird in the family Alcedinidae. It is endemic to the Society Islands of French Polynesia. Its natural habitats are subtropical or tropical moist lowland forest and subtropical or tropical moist montane forest.
Winchell's kingfisher or the rufous-lored kingfisher, is a species of bird in the family Alcedinidae, the kingfishers. It is endemic to the Philippines, its natural habitat being lowland forests. It is threatened by deforestation, and the International Union for Conservation of Nature (IUCN) has assessed it as a vulnerable species.
