Interesting.

This looks like Raddes or Yellow-streaked Warbler to me. . . too olive for Dusky Warbler.

Since the bill is rather slim and pointy I favour Yellow-steeaked, but I would be interested to hear other opinions.

Thanks, Mike.

I think this is a Dusky Warbler.
The slender bill and legs seem to favour that species. Also the relatively poor supercilium (especially behind the eye) and dark eye-stripe.
First-year birds are typically more olive in colour than adults, and this bird appears to be within the range of variation for the species.

Radde's should show a longer supercilium, heavier bill and thicker legs. I don't have much experience with Yellow-streaked, but I think it also has thicker legs, (slightly) thicker bill and a longer, more prominent supercilium. Also I think it should be slightly yellower underneath.

It would also help if you noticed the call.
