Leaf warblers are small insectivorous passerine birds belonging to the genus Phylloscopus.
The wood warbler is a common and widespread leaf warbler which breeds throughout northern and temperate Europe, and just into the extreme west of Asian Russia in the southern Ural Mountains.
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 yellow-vented warbler is a species of leaf warbler. It was formerly included in the "Old World warbler" assemblage.
Hartert's leaf warbler is a leaf warbler found only in China. Its natural habitats are temperate forests and subtropical or tropical moist lowland forests. It was previously considered a subspecies of Blyth's leaf warbler.
The black-capped woodland warbler is a leaf warbler species in the family Phylloscopidae; it was formerly placed in the "Old World warbler" assemblage.
Ijima's leaf warbler is a species of Old World warbler in the family Phylloscopidae. It is found in Japan, the Philippines, and Taiwan. Its natural habitats are subtropical or tropical dry forests, subtropical or tropical moist lowland forests, and subtropical or tropical moist shrubland. It is threatened by habitat loss, but is locally abundant in steep and densely wooded areas whose topography makes habitat destruction for development difficult. Ijima's leaf warbler is in practice hard to tell apart from the eastern crowned warbler, by physical appearance alone. It has the same dainty and perfectly proportioned features of the typical Phylloscopus warbler. However, the song - a series of quiet but fairly far-carrying squeaking sounds - is very different from the plaintive, Old World bunting-like song of the eastern crowned warbler.
The ashy-throated warbler is a species of leaf warbler. It was formerly included in the "Old World warbler" assemblage.
The buff-barred warbler is a species of leaf warbler. It was formerly included in the "Old World warbler" assemblage.
The yellow-throated woodland warbler is a species of Old World warbler in the family Phylloscopidae. It is found in Eswatini, Kenya, Malawi, Mozambique, South Africa, Tanzania, Zambia, and Zimbabwe. Its natural habitats are subtropical or tropical dry forest and subtropical or tropical moist lowland forest.
The buff-throated warbler is a species of leaf warbler. It was formerly included in the "Old World warbler" assemblage.
Brooks's leaf warbler is a species of Old World warbler in the family Phylloscopidae.
The mountain leaf warbler is a songbird species from the leaf warbler family (Phylloscopidae). 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.
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 limestone leaf warbler is a species of warbler in the family Phylloscopidae. When this species was first seen, beginning in 1994, it was mistaken for the similar sulphur-breasted warbler. It is smaller than the sulphur-breasted warbler, and has more rounded wings. The plumage is almost identical, with comparisons showing only a slightly colder yellow below and a greyer tinge above. Although smaller, the bill is proportionally larger than that of the sulphur-breasted warbler. Accurate measurements are not available; the holotype has a wing length of 5.2 centimetres (2.0 in); the paratype a tail length of 3.7 centimetres (1.5 in) and a bill length of 1.39 centimetres (0.55 in). The species is known to occur in northern Vietnam and Laos, and potentially also occurs in southern China as well. The species name, calciatilis, means "dwelling on limestone", which along with its common name is a reference to its natural habitat, which is broadleaved evergreen and semi-evergreen forest growing around limestone karst mountains. The bare-faced bulbul, described in 2009, was found in the karst of the same region.
