The '''Eastern Bonelli's warbler''' ('''''Phylloscopus orientalis'''''), 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:<ref>Parkin, David T. (2003): Birding and DNA: species for the new millennium. ''Bird Study'' '''50'''(3): 223–242.</ref><ref>Sangster, George; Knox, Alan G.; Helbig, Andreas J. & Parkin, David T.

* [[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 breeding ranges of the two species do not overlap; while their appearance and songs are very similar, the calls are completely different (see below). They also show marked difference in [[mtDNA]] [[DNA sequence|sequence]].<ref>Helbig, A. J.; Seibold, I.; Martens, J. & Wink, M. (1995): Genetic differentiation and phylogenetic relationships of Bonelli's Warbler ''Phylloscopus bonelli'' and Green Warbler ''P. nitidus''. ''[[Journal of Avian Biology|J. Avian Biol.]]'' 26: 139–153.</ref>

The species is [[bird migration|migratory]], wintering in sub-[[Sahara]]n [[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.<ref>Helb, H.-W.; Bergmann, H.-H. & Martens, J. (1982): Acoustic differences between populations of western and eastern Bonelli's Warblers (''Phylloscopus bonelli'', Sylviidae). ''Cellular and Molecular Life Sciences'' 38(3): 356–357.</ref>

The genus name ''Phylloscopus'' is from [[Ancient Greek]] ''phullon'', "leaf", and ''skopos'', "seeker" (from ''skopeo'', "to watch"). The specific ''orientalis'' is [[Latin]] for "eastern".<ref name=job>{{cite book | last= Jobling | first= James A | year= 2010| title= The Helm Dictionary of Scientific Bird Names | url= https://archive.org/details/Helm_Dictionary_of_Scientific_Bird_Names_by_James_A._Jobling | publisher= Christopher Helm | location = London | isbn = 978-1-4081-2501-4 | pages = [https://archive.org/details/Helm_Dictionary_of_Scientific_Bird_Names_by_James_A._Jobling/page/n284 284], 305}}</ref> The English name for this bird commemorates the Italian ornithologist [[Franco Andrea Bonelli]].<ref>{{cite book|last=Beolens|first=Bo|title=Whose Bird?
