Western Bonelli's Warbler
Western Bonelli's Warbler is a "warbler" in the leaf warbler genus Phylloscopus. 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:
- Western Bonelli's Warbler, Phylloscopus bonelli, which breeds in south west Europe and north Africa
- Eastern Bonelli's Warbler, Phylloscopus orientalis, which breeds in south east 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 sequence.
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.
