Hyliotidae
The hyliotas are a genus, ''Hyliota'', of passerine bird from Africa. The taxonomic position of the genus has been a longstanding mystery. They have been formerly regarded as Old World warblers in the family Sylviidae, or related to the batises and wattle-eyes in the family Platysteiridae, bush-shrikes in the family Malaconotidae, or even Old-World flycatchers in the family Muscicapidae. An analysis of the mitochondrial DNA of the genus and possible relatives found they have no close relatives and are basal in the clade Passerida. They are now often regarded as a family in their own right, Hyliotidae. The hyliotas are found in the canopy of broad-leaf forests. They usually do not live in groups but will join mixed-species feeding flocks with other species. They are territorial and pairs are monogamous, nesting in camouflaged woven nests. Species ''Hyliota'' contains the following species: * Southern hyliota (''Hyliota australis'') * Yellow-bellied hyliota (''Hyliota flavigaster' ...

Passerine
A passerine () is any bird of the order Passeriformes (; from Latin 'sparrow' and '-shaped'), which includes more than half of all bird species. Sometimes known as perching birds, passerines are distinguished from other orders of birds by the arrangement of their toes (three pointing forward and one back), which facilitates perching. With more than 140 families and some 6,500 identified species, Passeriformes is the largest clade of birds and among the most diverse clades of terrestrial vertebrates, representing 60% of birds.Ericson, P.G.P. et al.

William John Swainson
William John Swainson FLS, FRS (8 October 1789 – 6 December 1855), was an English ornithologist, malacologist, conchologist, entomologist and artist. Life Swainson was born in Dover Place, St Mary Newington, London, the eldest son of John Timothy Swainson the Second (1756–1824), an original fellow of the Linnean Society. He was cousin of the amateur botanist Isaac Swainson.Etymologisches Worterbuch der botanischen Pflanzennamen by H. Genaust. Review by Paul A. Fryxell ''Taxon'', Vol. 38(2), 245–246 (1989). His father's family originated in Lancashire, and both grandfather and father held high posts in Her Majesty's Customs, the father becoming Collector at Liverpool. William, whose formal education was curtailed because of an impediment in his speech, joined the Liverpool Customs as a junior clerk at the age of 14."William Swainson F.R.S, F.L.S., Naturalist and Artist: Diaries 1808–1838: Sicily, Malta, Greece, Italy and Brazil."

Old World Warbler
Old World warblers are a large group of birds formerly grouped together in the bird family Sylviidae. The family held over 400 species in over 70 genera, and were the source of much taxonomic confusion. Two families were split out initially, the cisticolas into Cisticolidae and the kinglets into Regulidae. In the past ten years they have been the subject of much research and many species are now placed into other families, including the Acrocephalidae, Cettiidae, Phylloscopidae, and Megaluridae. In addition some species have been moved into existing families or have not yet had their placement fully resolved. A smaller family of warblers, together with some babblers formerly placed in the family Timaliidae and the parrotbills, are retained in a much smaller family Sylviidae. Characteristics Most Old World warblers are of generally undistinguished appearance, though some Asian species are boldly marked. The sexes are often identical, but may be clearly distinct, notably in the ge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sylviidae
Sylviidae is a family of passerine birds that includes the typical warblers and a number of babblers formerly placed within the Old World babbler family. They are found in Eurasia and Africa. Taxonomy and systematics The scientific name Sylviidae was introduced by the English zoologist William Elford Leach (as Sylviadæ) in a guide to the contents of the British Museum published in 1820. The family became part of an assemblage known as the Old World warblers and was a wastebin taxon with over 400 species of bird in over 70 genera. Advances in classification, particularly helped with molecular data, have led to the splitting out of several new families from within this group. There is now evidence that these ''Sylvia'' "warblers" are more closely related to the Old World babblers than the warblers and thus these birds are better referred to as Sylvia babblers, or just sylviids. A molecular phylogenetic study using mitochondrial DNA sequence data published in 2011 found that the s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Platysteiridae
Platysteiridae is a family of small, stout passerine birds of the African tropics. The family contains the wattle-eyes, batises and shrike-flycatchers. They were previously classed as a subfamily of the Old World flycatchers, Muscicapidae. These insect-eating birds are usually found in open forests or bush. They hunt by flycatching, or by taking prey from the ground like a shrike. The nest is a small, neat cup, placed low in a tree or bush. Distribution and habitat The Platysteiridae are arboreal birds, primarily of the woodlands and forests of sub-Saharan Africa. The family is restricted to mainland Africa and its offshore islands. The shrike-flycatchers and genus ''Dyaphorophyia'' are inhabitants of dense forest, while the rest of the wattle-eyes are found in woodland, and the batises range across all wooded habitats except the densest forests of the Congo Basin. The pririt and pygmy batis survive in very arid environments with some cover, and the white-fronted wattle-eye ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Muscicapidae
The Old World flycatchers are a large family, the Muscicapidae, of small passerine birds restricted to the Old World (Europe, Africa and Asia), with the exception of several vagrants and two species, Bluethroat (''Luscinia svecica)'' and Northern Wheatear (''Oenanthe oenanthe''), 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 includes 344 species and is divided into 51 genera. Taxonomy The name Muscicapa for the family was introduced by the Scottish naturalist John Fleming in 1822. The word had earlier been used for the genus ''Muscicapa'' by the French zoologist Mathurin Jacques Brisson in 1760. Muscicapa comes from the Latin ''musca'' meaning a fly and '' capere'' to catch. In 1910 the German ornithologist Ernst Hartert found it impossible to define boundaries between the three families Muscicapidae, Sylviidae (Old World warblers) and Turdidae (thrushes). He therefore treat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mitochondrial DNA
Mitochondrial DNA (mtDNA or mDNA) is the DNA located in mitochondria, cellular organelles within eukaryotic cells that convert chemical energy from food into a form that cells can use, such as adenosine triphosphate (ATP). Mitochondrial DNA is only a small portion of the DNA in a eukaryotic cell; most of the DNA can be found in the cell nucleus and, in plants and algae, also in plastids such as chloroplasts. Human mitochondrial DNA was the first significant part of the human genome to be sequenced. This sequencing revealed that the human mtDNA includes 16,569 base pairs and encodes 13 proteins. Since animal mtDNA evolves faster than nuclear genetic markers, it represents a mainstay of phylogenetics and evolutionary biology. It also permits an examination of the relatedness of populations, and so has become important in anthropology and biogeography. Origin Nuclear and mitochondrial DNA are thought to be of separate evolutionary origin, with the mtDNA being derived ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mixed-species Feeding Flock
A mixed-species feeding flock, also termed a mixed-species foraging flock, mixed hunting party or informally bird wave, is a flock of usually insectivorous birds of different species that join each other and move together while foraging. These are different from feeding aggregations, which are congregations of several species of bird at areas of high food availability. While it is currently unknown how mixed-species foraging flocks originate, researchers have proposed a few mechanisms for their initiation. Many believe that nuclear species play a vital role in mixed-species flock initiation. Additionally, the forest structure is hypothesized to play a vital role in these flocks' formation. In Sri Lanka, for example, vocal mimicry by the greater racket-tailed drongo might have a key role in the initiation of mixed-species foraging flocks, while in parts of the American tropics packs of foraging golden-crowned warblers might play the same role.
