Seicercus is a genus of Old World warbler formerly in the family Sylviidae but now placed in Phylloscopidae. [1] Recent scientific studies have recommended synonymizing this genus with Phylloscopus, [2] and are placed there.
The genus is distributed in the Indian subcontinent and eastern Asia from northern China to Timor in the Lesser Sundas. Many of the more northerly species are migratory, breeding in temperate climates and wintering in the tropics; others are attitudinal migrants, moving down from the mountains in the winter. A few species are migratory over part of their range and resident in others. [3]
The Seicercus warblers are small passerines that range in size from 9.5 to 12 cm in length and weigh around 4-9 g. [3] All species have green wings and yellow bellies, most have yellow breasts as well. The head is either grey, green or buff/brown, and all species have stripes on the crown or face as well as a yellow or white eye-ring. The sexes are similar to each other.
Seicercus warblers feed on insects, usually obtained by gleaning and short sally flights. [3] A few species associate with mixed-species feeding flocks. Different species feed in different parts of the forest, some, like the chestnut-crowned warbler feed in the canopy whereas the Sunda warbler prefers the understory and lower canopy.
It contained the following species:
Grey-hooded warbler (Phylloscopus xanthoschistos) was formerly included in this genus.
The species known as golden-spectacled warblerSeicercus burkii (Sibley and Monroe 1990, 1993) was split into S. burkii, S. valentini, S. whistleri, S. soror and S. tephrocephalus following Alström & Olsson (1999) and S. omeiensis following Martens et al. (1999).
Old World warblers are a large group of birds formerly grouped together in the bird family Sylviidae. They are not closely related to the New World warblers. 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 number of warblers, together with some babblers formerly placed in the family Timaliidae and the parrotbills, are retained in a much smaller family Sylviidae.
Leaf warblers are small insectivorous passerine birds belonging to the genus Phylloscopus.
The greenish warbler is a widespread leaf warbler with a breeding range in northeastern Europe, and temperate to subtropical continental Asia. This warbler is strongly migratory and winters in India. It is not uncommon as a spring or early autumn vagrant in Western Europe and is annually seen in Great Britain. In Central Europe large numbers of vagrant birds are encountered in some years; some of these may stay to breed, as a handful of pairs does each year in Germany.
The green warbler, also known as green willow warbler or green leaf warbler, is a leaf warbler found in the Caucasus Mountains in southeastern Europe.
The large-billed leaf warbler is a species of migratory leaf warbler found in Asia.
Davison's leaf warbler or the white-tailed leaf warbler, is a species of leaf warbler. It was formerly included in the "Old World warbler" assemblage.
The Emei leaf warbler is a species of leaf warbler. It was formerly included in the "Old World warbler" assemblage.
Kloss's leaf warbler is a leaf warbler found in Cambodia, China, Laos, Thailand, and Vietnam. Its natural habitats are temperate forests, subtropical or tropical moist lowland forests, and subtropical or tropical moist montane forests.
The white-spectacled warbler is a species of leaf warbler in the family Phylloscopidae. It is found in Asia from the eastern Himalayas to south-eastern China and southern Vietnam. Its natural habitats are subtropical or tropical moist lowland forests and subtropical or tropical moist montane forests. It was formerly included in the Old World warbler family, Sylviidae.
The green-crowned warbler is a species of leaf warbler. It was formerly included in the "Old World warbler" assemblage.
The chestnut-crowned warbler is a species of leaf warbler. It was formerly included in the "Old World warbler" assemblage.
The Sunda warbler is a species of Old World warbler in the family Phylloscopidae. It is found only in Indonesia.
Martens's warbler, also known as Omei warbler or Emei Shan warbler, is a species of Old World warbler in the family Phylloscopidae. It was first described in 1999. It is found in China and Myanmar. Its natural habitats are temperate forests and subtropical or tropical moist montane forests.
The grey-cheeked warbler is a species of leaf warbler. It was formerly included in the "Old World warbler" assemblage.
Alström's warbler, or the plain-tailed warbler, is a species of Old World warbler in the family Phylloscopidae. It was first described in 1999. It breeds only in China and winters as far as Thailand, Laos, Cambodia and Vietnam. Its natural habitat is temperate forests.
The grey-crowned warbler is a species of Old World warbler in the family Phylloscopidae. It is found in Bangladesh, China, India, Laos, Myanmar, Thailand and Vietnam. Its natural habitats are temperate forests, subtropical or tropical moist lowland forest, and subtropical or tropical moist montane forest.
Bianchi's warbler is a species of leaf warbler. It was formerly included in the "Old World warbler" assemblage.
Whistler's warbler is a species of leaf warbler. It was formerly included in the "Old World warbler" assemblage.
The tesias are a genus, Tesia, of Old World warbler. Though once included in the large family Sylviidae, more recent research placed it within a new family, Cettiidae. The four species inhabit undergrowth of montane forest in South and Southeast Asia, where they are resident or short-range migrants. They have longish legs and appear tailless, with (seemingly) only 8 rectrices. Their simple songs are fairly loud, and their nests are typically ball-shaped. Their name is derived from Tisi, the Nepalese name for the grey-bellied tesia.
Golden-spectacled warbler was a common name for birds in the Seicurcus burkii species complex, which included birds now known as:
