Leaf warblers are small insectivorous passerine birds belonging to the genus Phylloscopus.
The Arctic warbler is a widespread leaf warbler in birch or mixed birch forest near water throughout its breeding range in Fennoscandia and the northern Palearctic. It has established a foothold in North America, breeding in Alaska. This warbler is strongly migratory; the entire population winters in southeast Asia. It therefore has one of the longest migrations of any Old World insectivorous bird.
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.
Pallas's leaf warbler or Pallas's warbler, is a bird that breeds in mountain forests from southern Siberia east to northern Mongolia and northeast China. It is named for German zoologist Peter Simon Pallas, who first formally described it. This leaf warbler is strongly migratory, wintering mainly in south China and adjacent areas of southeast Asia, although in recent decades increasing numbers have been found in Europe in autumn.
The yellow-browed warbler is a leaf warbler which breeds in the east Palearctic. This warbler is strongly migratory and winters mainly in tropical South Asia and South-east Asia, but also in small numbers in western Europe. Like the rest of Phylloscopidae, it was formerly included in the Old World warbler assemblage.
Hume's leaf warbler or Hume's warbler is a small leaf warbler which breeds in the mountains of inner Asia. This warbler is migratory and winters mainly in India.
The western Bonelli's warbler is a warbler in the leaf warbler genus Phylloscopus. It was formerly regarded as the western subspecies of a wider "Bonelli's warbler" species, but as a result of modern taxonomic developments, they are now usually considered to be two species:
The Eastern Bonelli's warbler, sometimes known as Balkan warbler, is a "warbler" in the leaf warbler genus Phylloscopus. It was formerly regarded as the eastern subspecies of a wider "Bonelli's warbler" species, but as a result of modern taxonomic developments, they are now usually considered to be two species:
The yellow-vented warbler is a species of leaf warbler. It was formerly included in the "Old World warbler" assemblage.
The ashy-throated warbler is a species of leaf warbler. It was formerly included in the "Old World warbler" assemblage.
Blyth's leaf warbler is a species of leaf warbler. It was formerly included in the "Old World warbler" assemblage.
The buff-throated warbler is a species of leaf warbler. It was formerly included in the "Old World warbler" assemblage.
The grey-hooded warbler is a species of leaf warbler. It is most famous for the way it warbles. It was formerly included in the "Old World warbler" assemblage.
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 grey-cheeked warbler is a species of leaf warbler. It was formerly included in the "Old World warbler" assemblage.
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 Kamchatka leaf warbler is a species of leaf warbler. It was formerly included in the "Old World warbler" assemblage. It is closely related to the Arctic warbler and the Japanese leaf warbler, to which it was formerly considered conspecific.
The Japanese leaf warbler is a leaf warbler. The species was first described by Robert Swinhoe in 1863. It was formerly included in the "Old World warbler" assemblage. It is closely related to the Arctic warbler and the Kamchatka leaf warbler, to which it was formerly considered conspecific.
