The western Bonelli's warbler (Phylloscopus bonelli) 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, 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 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 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"). Wikipedia →

Global Distribution

Where this species is recorded worldwide. Restricted to human observations from 2019 onwards — the same kind of record and the same period the probabilities on this page are built from, so collar-tracking studies, camera-trap arrays and museum specimens are excluded. Around Santa Rosa that removes 5,924 GPS fixes from a handful of tagged jaguars.
