Tree Warbler
Tree warblers are medium-sized warblers in the marsh- and tree-warbler family Acrocephalidae. They are found in Europe, Africa and western Asia. Until recently, they were all classified in the single genus ''Hippolais''. These warblers are associated with trees, though normally in fairly open woodland rather than tight plantations. Compared with the closely related '' Acrocephalus'' species, tree warblers have squarer tails and broader bill-bases. Most are unstreaked greenish or brownish above and cream or white below. They are insectivorous, but will occasionally take berries or seeds. The species breeding in temperate regions are mostly strongly migratory. Taxonomy All the tree warblers were formerly placed in the "Old World warbler" family Sylviidae but are now separated in the family Acrocephalidae, along with the marsh warblers, '' Acrocephalus'', and some related species. Considerable evidence, much of it summarised in Parkin et al. (2004), suggests that the genus '' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hippolais
''Hippolais'' is a genus of tree warbler in the family Acrocephalidae. It is sometimes associated with the genus '' Iduna''. The genus name ''Hippolais'' is from Ancient Greek ''hupolais'', as misspelt by Linnaeus. It referred to a small bird mentioned by Aristotle Aristotle (; grc-gre, Ἀριστοτέλης ''Aristotélēs'', ; 384–322 BC) was a Greek philosopher and polymath during the Classical period in Ancient Greece. Taught by Plato, he was the founder of the Peripatetic school of ph ... and others and may be onomatopoeic or derived from ''hupo'',"under", and ''laas'', "stone".

British Ornithologists' Union Records Committee
The British Ornithologists' Union (BOU) aims to encourage the study of birds ("ornithology") and around the world, in order to understand their biology and to aid their conservation. The BOU was founded in 1858 by Professor Alfred Newton, Henry Baker Tristram and other scientists. Its quarterly journal, ''Ibis'', has been published continuously since 1859. The Records Committee (BOURC) is a committee of the BOU established to maintain the British List, the official list of birds recorded in Great Britain. BOU is headquartered in Peterborough and is a registered charity in England & Wales and Scotland. Objectives and activities * Publishes ''Ibis'' as a leading international journal of ornithological science. * Organises a programme of meetings and conferences. * Awards grants and bursaries for ornithological research. * Encourages liaison between those actively engaged in ornithological research. * Provides a representative body of the scientific community able to provide o ...

Upcher's Warbler
Upcher's warbler (''Hippolais languida'') is an Old World warbler in the tree warbler genus ''Hippolais''. It breeds in an area from Turkey south and east to Pakistan. It is migratory, wintering in eastern Africa, from Eritrea and Somalia south to Tanzania. This small passerine bird is a species found in semi-desert habitats, frequenting bushy scrub and thickets of tamarisk. Four or five eggs are laid in a nest in bushes and low trees. This is a medium-sized warbler, similar in size to the icterine warbler, with a slightly longer bill and shorter wings and a longer tail. Its frequent tail movement is reminiscent of a '' Sylvia'' warbler or a chat. Its rather grey plumage is similar to the olivaceous warbler, but tail movements are diagnostic. It feeds on invertebrates. Its song is similar to that of other ''Hippolais'' warblers, but distinctive and unmistakable, and entirely different from that of the olivaceous warbler. Ehrenberg's original description of this bird was 'rat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
African Yellow Warbler
The African yellow warbler (''Iduna natalensis''), also known as Natal yellow warbler, dark-capped yellow warbler or yellow flycatcher-warbler, is a species of Acrocephalidae warblers; formerly, these were placed in the paraphyletic "Old World warblers". Description The African yellow warbler is a medium-sized warbler in which the whole of the upperparts and tail are yellowish-brown, with a slightly browner crown and yellower rump. The wings have brown feathers edged with yellow. The underparts are bright yellow with an olive wash on the sides of the breast, flanks and lower belly. The bill is pale on the upper mandible and blackish on the lower, and the legs are blackish. Females have duller underparts, and the juveniles are similar to the males but are buffier. The total length is and the birds weigh between . Voice The song of the African yellow warbler is a rapid series of throaty and varied notes preceded by a few raspy notes, for example, "''chip-chip-chip- whee-lee-wheeo' ...

Eastern Olivaceous Warbler
The eastern olivaceous warbler (''Iduna pallida'') is a small passerine bird with drab plumage tones, that is native to the Old World. For the most part it breeds in southeastern Europe, the Middle East and adjacent western Asia, and winters in the northern Afrotropics. Relationships The eastern olivaceous warbler (''Iduna pallida'') is a "warbler", formerly placed in the Old World warblers when these were a paraphyletic wastebin taxon. It is now considered a member of the acrocephaline warblers, Acrocephalidae, in the tree warbler genus ''Iduna''. It was formerly regarded as part of a wider "olivaceous warbler" species, but as a result of modern taxonomic developments, this species is now usually considered distinct from the western olivaceous warbler, ''Iduna opaca''. Etymology Keyserling and Blasius gave no explanation of the genus name ''Iduna''. The specific ''pallida'' is Latin for "pale". Habits This small passerine bird is found in dry open country, including cultiv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Western Olivaceous Warbler
The western olivaceous warbler (''Iduna opaca''), also known as isabelline warbler, is a "warbler", formerly placed in the Old World warblers when these were a paraphyletic wastebin taxon. It is now considered a member of the acrocephaline warblers, Acrocephalidae, in the tree warbler genus ''Iduna''. It was formerly regarded as part of a wider "olivaceous warbler" species, but as a result of modern taxonomic developments, this species is now usually considered distinct from the eastern olivaceous warbler, ''Iduna pallida''. It is a small passerine bird, found in dry open country, including cultivation, with bushes or some trees. Two or three eggs are laid in a nest in low undergrowth or a bush. Like most warblers, the western olivaceous warbler is insectivorous. It is a medium-sized warbler, more like a very pale reed warbler than its relative the melodious warbler. The adults have a plain pale brown back and whitish underparts. The bill is strong and pointed and the legs gre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sykes's Warbler
Sykes's warbler (''Iduna rama'') is an Old World warbler in the tree warbler family. It was formerly considered a subspecies of the booted warbler, but is now considered a full species. Its breeding range is from northeast Arabia to Turkestan, west China and Afghanistan. Like the booted warbler, many populations of the species migrate in winter to the Indian subcontinent as far south as Sri Lanka. Etymology The English name commemorates the Colonel William Henry Sykes who served in the British military in India. Keyserling and Blasius gave no explanation of the genus name ''Iduna'', though in Norse mythology Iðunn, or Iduna, is the goddess of spring and fertility who was changed into a sparrow to enable her rescue by Loki. The specific epithet ''rama'' refers to the Hindu god Rama, an incarnation of Vishnu. Taxonomy Molecular phylogeny studies in 2009 suggested a clade sister to '' Chloropeta'' and separate from ''Hippolais'' in the strict sense resulting in the removal of ...

Booted Warbler
The booted warbler (''Iduna caligata'') is an Old World warbler in the tree warbler group. It was formerly considered to be conspecific with Sykes's warbler, but the two are now usually both afforded species status. Booted warbler itself breeds from central Russia to western China, and migrates to winter in the Indian subcontinent as far south as Sri Lanka. Booted warbler has expanded its breeding range westward in recent decades and nests now as far west and north as Finland. It is a small passerine bird, found in open country with bushes and other tall vegetation. Three or four eggs are laid in a nest in a bush or vegetation. Like most warblers they are insectivorous. These are small warblers, especially compared to others in their genus. They are pale brown above and whitish below with buff flanks. The outer tail feathers have pale edges. They have a short pale supercilium, and the bill is strong and pointed. Sykes's warbler is larger and greyer than the booted warbler, and ...

Thick-billed Warbler
The thick-billed warbler (''Arundinax aedon'') breeds in the temperate east Palearctic, from south Siberia to west Mongolia. It is migratory, wintering in tropical South Asia and South-east Asia. It is a very rare vagrant to western Europe. This passerine bird is a species found in dense vegetation such as reeds, bushes and thick undergrowth. Five or six eggs are laid in a nest in a low tree. This is a large warbler, at long, which is nearly as big as the great reed warbler. The adult has an unstreaked brown back and buff underparts, with few obvious distinctive plumage features. The forehead is rounded, and the bill is short and pointed. The sexes are identical, as with most warblers, but young birds are richer buff below. Like most warblers, it is insectivorous, but will take other small prey items. The song is fast and loud, and similar to the marsh warbler, with much mimicry and typically acrocephaline whistles added. It was sometimes placed in the monotypic genus ''Phr ...
