Frequenting scrub, hedges, orchards, and woodland.
The Bonelli's warbler lacks any striking features and is a rather plain grey bird. In flight the yellow rump and coverts can help identification. The Eastern Bonnelli's Warbler is now considered a separate species and is even greyer than the Western bird lacking the yellow coverts.
The Bonelli's call is finch like: a quite 'whee-eet'
Its song is a slow trill not unlike a slower version of the Wood Warblers song.
Species: P. Bonelli(Eastern) P.orientalis(Western)
