Phylloscopus orientalis

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: Western Bonelli's warbler, Phylloscopus bonelli, which breeds in southwest Europe and north Africa - Eastern Bonelli's warbler, Phylloscopus orientalis, which breeds in southeast Europe and Asia Minor The species is migratory, wintering in sub-Saharan Africa. It is a rare vagrant in Northern Europe. Eastern Bonelli's warbler is a small passerine bird, found in forest and woodland. Four to six eggs are laid in a nest on the ground. Like most warblers, eastern Bonelli's is insectivorous. It is a small warbler. The adult has a plain grey-green back, green-toned rump and wings and whitish underparts. The bill is small and pointed and the legs brown. The sexes are identical, as with most warblers. The eastern Bonelli's warbler lacks the browner tinge to the upperparts that the western Bonelli's warbler has; it sometimes has a greenish tinge instead. The song is a fast monotone trill, only slightly different from western Bonelli's, and also some similarity to the wood warbler. The call of the eastern Bonelli's warbler is a hard chup, reminiscent of a crossbill or a house sparrow, and completely different from the disyllabic hu-it of the western Bonelli's warbler.
