It was formerly regarded as the western subspecies of a wider "Bonelli's warbler" species, but as a result of modern taxonomic developments, this species is now usually considered to be two species:[2][3]
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 sequence.[4] The species is migratory, wintering in sub-Saharan Africa. It is a rare vagrant in Northern Europe. The genus name Phylloscopus is from Ancient Greek phullon, "leaf", and skopos, "seeker" (from skopeo, "to watch").[5] The English name and the specific bonelli are for the Italian ornithologist Franco Andrea Bonelli.[6] DescriptionWestern Bonelli's warbler is a small passerine bird, found in forest and woodland. 4–6 eggs are laid in a nest on the ground. Like most warblers, western Bonelli's is insectivorous. 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 western Bonelli's warbler has a browner tinge to the upperparts than eastern Bonelli's warbler; the latter sometimes has a greenish tinge instead. The song is a fast monotone trill, only slightly different from eastern Bonelli's, and also some similarity to wood warbler. The call of the western Bonelli's warbler is a disyllabic hu-it, differing from that of eastern which is a completely different hard chup, reminiscent of a crossbill or a house sparrow.[7] References1. ^{{IUCN|id=22715255 |title=Phylloscopus bonelli |assessor=BirdLife International |assessor-link=BirdLife International |version=2013.2 |year=2012 |accessdate=26 November 2013}} 2. ^Parkin, David T.
