Bonelli's Warbler, Phylloscopus bonelli, is an Old World warbler in the leaf warbler genus Phylloscopus. As a result of modern taxonomic developments, it is now usually considered to be two species, Western Bonelli's Warbler , Phylloscopus bonelli, and Eastern Bonelli's Warbler, Phylloscopus orientalis.
These small passerine birds are found in forest and woodland. 4-6 eggs are laid in a nest on the ground. Like most warblers, Bonelli's is insectivorous.
These are small warblers. The adults of both species have a plain grey-green back and whitish underparts. The bill is small and pointed and the legs brown. The sexes are identical, as with most warblers.
Western Bonelli's Warbler breeds in south west Europe and north Africa, and Eastern Bonelli's Warbler in south west Europe. Both species are migratory, wintering in sub-Saharan Africa. They are rare vagrants in Northern Europe.
Western Bonelli's Warbler has a browner tinge to the upperparts than Eastern Bonelli's Warbler. Eastern Bonelli's Warbler sometimes has a greenish tinge to its upperparts. The song of both species is a fast monotone, but they are not the same. The call is a disyllabic hu-it
This bird is named after the Italian ornithologist Franco Andrea Bonelli.
