Adult Male and Female
Distribution:
Very rare vagrant to the UK, widespread across Southern Europe, returning to Africa to winter. Most likely to appear as a vagrant to any area in the UK August/September.
Habitat:
Frequenting scrub, hedges, orchards, and woodland.
Notes:
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.
