The akalats (stressed on the second syllable) [2] are medium-sized insectivorous birds in the genus Sheppardia. They were formerly placed in the thrush family, Turdidae, but are more often now treated as part of the Old World flycatcher family, Muscicapidae.
The genus contains 11 Sub-Saharan forest-dwelling species: [3]
The genus Sheppardia was introduced in 1909 by the South African ornithologist Alwin Karl Haagner with the East coast akalat (Sheppardia gunningi) as the type species. [5] The name of the genus was chosen to honour the collector and farmer P. A. Sheppard. [5] [6] [7]
Richard Bowdler Sharpe, who had never visited Africa, associated the akalats, in their Bulu appellation, with birds of "different kinds" occurring in the forest understorey. [8] His main collector in West Africa, George L. Bates, denoted them more specifically as "little members of the genus Turdinus, which are called in Fang and Bulu "Akalat"....". [9] The latter genus denoted a group of Old World babblers, currently classed as near-babblers in the genus Illadopsis .
David Armitage Bannerman's volumes on West African birds, published from 1930 through to 1951, became well-established reference works for the region, and retained the name akalat for Trichastoma, which is Illadopsis. Reichenow however classed Turdinus batesi as an Alethe , [10] then in the Turdidae (thrushes and flycatchers), followed by Jackson and Sclater in 1938 who applied it to Sheppardia specifically. [11] Mackworth-Praed and Grant (1953, 1955) and Williams (1963 - 1980s) retained their usage. In 1964 the name was still recorded as denoting both groups, namely the Malococincla, i.e. Illadopsis near-babblers in West Africa, and the Sheppardia chats in East African literature, [12] though the latter convention prevailed in modern times.
Yet the calls of the aforementioned species only doubtfully agree with the akalat's appellation as an omen of death. It is recorded that the akalat's forest song, respectively referred to as "boofio" and "woofio" by the Bulu and Ntumu peoples, is believed by them to predict the death of a near parent who bids them farewell with this song. [13]
The east coast akalat or Gunning's robin is a small passerine bird which can be found in the east of Africa from Kenya to Mozambique, and is named after J. W. B. Gunning.
The thrushes are a passerine bird family, Turdidae, with a worldwide distribution. The family was once much larger before biologists reclassified the former subfamily Saxicolinae, which includes the chats and European robins, as Old World flycatchers. Thrushes are small to medium-sized ground living birds that feed on insects, other invertebrates, and fruit. Some unrelated species around the world have been named after thrushes due to their similarity to birds in this family.
The Old World flycatchers are a large family, the Muscicapidae, of small passerine birds restricted to the Old World, with the exception of several vagrants and two species, bluethroat and northern wheatear, found also in North America. These are mainly small arboreal insectivores, many of which, as the name implies, take their prey on the wing. The family is relatively large and includes 351 species, which are divided into 54 genera.
Alethe is a genus of small mainly insectivorous birds in the Old World flycatcher family Muscicapidae that occur in West Africa.
Cossypha are small insectivorous birds, with most species called robin-chats. They were formerly in the thrush family Turdidae, but are now more often treated as part of the Old World flycatcher Muscicapidae.
The cochoas are medium-sized frugivorous, insectivorous and molluscivorous birds in the genus Cochoa. Their bright contrasting plumage patterns, sexual dimorphism and feeding habits made their systematic position difficult to ascertain in early times, Richard Bowdler Sharpe placed them with the Prionopidae in 1879 while many considered them as some kind of aberrant thrush. The genus was previously included in the Old World flycatcher family Muscicapidae but molecular phylogenetic studies have shown that it is more closely related to the thrush family Turdidae.
The palm thrushes are medium-sized insectivorous birds in the genus Cichladusa. They were formerly in the thrush family Turdidae, but are now treated as part of the Old World flycatcher Muscicapidae.
The magpie-robins or shamas are medium-sized insectivorous birds in the genus Copsychus. They were formerly in the thrush family Turdidae, but are now treated as part of the Old World flycatcher family Muscicapidae. They are garden- and forest-dwelling species found in Africa and Asia.
The mountain wheatear or mountain chat is a small insectivorous passerine bird that is endemic to southwestern Africa.
The Nilgiri blue robin, also known as Nilgiri shortwing, white-bellied shortwing, Nilgiri sholakili or rufous-bellied shortwing is a species of passerine bird in the family Muscicapidae endemic to the Shola forests of the higher hills of southern India, mainly north of the Palghat Gap. This small bird is found on the forest floor and undergrowth of dense forest patches sheltered in the valleys of montane grassland, a restricted and threatened habitat.
The grey-winged robin-chat or grey-winged akalat is a bird in the family Muscicapidae. The species was first described by Anton Reichenow in 1892.
Tessmann's flycatcher is a species of bird in the family Muscicapidae. It is sparsely distributed across the African tropical rainforest from Sierra Leone to the Democratic Republic of the Congo. Its natural habitat is subtropical or tropical moist shrubland.
Sharpe's akalat is a species of bird in the family Muscicapidae. It is found in Tanzania and northern parts of Zambia and Malawi. Its natural habitats are boreal forests and subtropical or tropical moist montane forests.
Jan Willem Boudewijn Gunning, was a Dutch physician, who served as the director of both the Staatsmuseum and what was then known as the Pretoria Zoological Gardens.
The jungle babblers are a family, Pellorneidae, of mostly Old World passerine birds belonging to the superfamily Sylvioidea. They are quite diverse in size and coloration, and usually characterised by soft, fluffy plumage and a tail on average the length of their body, or longer. These birds are found in tropical zones, with the greatest biodiversity in Southeast Asia and the Indian subcontinent.
