No Jayan, its a Blyth's Reed Warbler on account of face pattern with combination of dark loral line and supercilium widest in loral area extending beyond eye, bill with quite extensive dusky area proximally to lower mandible and uniform olive-brown upperparts, the latter too dark and wrong tone for Sykes's. Note too, the tail is very rounded i.e the central tail feathers (R1) are longest and outer tail feather (R6) is rather short whereas in Sykes's and Booted R1 is shorter than R2.

Absolutely not Ken, one cannot judge for certain which feathers are emarginated with the wing so 'bunched' + angle.

As I understood the BRW wing formula Grahame right or wrong, I was under the impression that BRW “should” show an emargination on P3 and sometimes P4 well within the overlying tertial area, which should place it well away from the “as seen” bunching?
Further, it must share the “booted” appearance with Booted/Sykes?

Ken, if you stating you can interpret the WF from the above you are simply kidding yourself.
Oh, and this was the very 1st Blyth's Reed image on eBird and, look, its got 'boots' ML81345741 - Blyth's Reed Warbler - Macaulay Library and another
ML81595361 - Blyth's Reed Warbler - Macaulay Library In short, there endless such examples.

Grahame yes, there are no doubt endless examples of “similar”.
Here’s perhaps a better “lightened” version of said bird.
I’m not kidding myself regarding what I can clearly see from the image wing formula.
You appear not to agree with my interpretation and comment, clearly?
Cheers

No, it's just hidden behind the body. It wouldn't be able to keep itself in this position (or even land on the twig like this) if it had only one leg.

BRW can show the emarginations but they are not always visible by any means as Grahame has said. I can't see any either on the photo in this instance either.

Since finding a BRW almost twenty five years ago (in a most unlikely setting).
I’ve been surprised by the numerous birds “claimed as” that, having appeared in media during the interim.
Unstreaked Acros without any emarges.shown (on good profile wing shots) and those with emarges. to far down the wing outside the tertial area, sporting longer primaries than should have.
It seems to me that certain claimed “features” for the species are “often” unhelpful and potentially misleading.
Dark tip to the bill being one, plus concolourously grey upperparts to include back and rump.
Neither of these features occurred on the 2020 London Canary Wharf bird, indeed it having a warm brown rump contrasting against a grey mantle when seen in direct sunlight.
Certainly a species that deserves more attention to detail imo.
Likewise, as far as the subject bird is concerned, I can’t see any real emarges.on p3 or p4 and the tail might have been subject to wear looking perhaps somewhat more rounded than should?
