Dusky Warbler, I am pretty sure.

Thanks......, just wondered about the dark line above the eye

My primary judgement is based on the feature that the rare part of the supercilium is more yellow than the part in front of the eye.  Indeed the dark like above the supercilium (and also the eye stripe) is a bit alarming.  But it seems Dusky Warbler can have individual variation to fit this bird.  See the link I list below.

Hi HFC.
Agree my image & the link show the same bird, but could raise the question as to whether the link is of a Dusky.
Have put my image in Bird Forum where the debate is between Dusky & Yellow-streaked.
Apart from the eyebrow line, concern is the thickness of the bill & legs which seem to be thicker than Dusky.
Variations are more likely to happen in plumage dependent on time of year & ambiant light.
I am going to see if I can get a sound byte this weekend which might help to sort it out.
Thanks.

Thanks for the input.
Neil & I went back to the same spot this morning and whilst I didn't see the chap, heard him all around us......, no recording device but both of us agreed is definitely a "tsic" and NOT a "tac".
Conclude we are looking at a [b]Yellow-streaked Warbler[/b]

Despite what you say about the call, to me this is a fairly typical adult winter Dusky Warbler.  It does have an obvious dark border above the supercilium which is regularly shown on both Radde's and Yellow-streaked, but it is also well known that some Dusky Warblers can show this.

Yellow-streaked is extremely similar to Radde's and can be very tricky to separate, the separation of Dusky and Yellow-streaked should not really be an issue.

This bird lacks the uniformly pale legs and feet, well defined supercilium behind the eye and thicker bill of Yellow-streaked (and Radde's).

This is also an adult (based on the bright undertail coverts and flanks and white belly); as such an adult Yellow-streaked would show obvious yellow streaks on the underparts - which this bird lacks.

Thanks Paul for your detailed reply.
I have amended the image in "warblers" to read "Dusky".
