The UTC’s appear to end at the tail tip Harry?
Possibly, hence why I'd like to see another pic if possible. If that feature is real and not due to an odd angle, it would overrule any passing resemblance to a Reed Warbler. I can see the appeal, and it may well be a Savi's, but this one image is playing with my head!

no way is this a savi's. it's an acro and as such most probably a reed warbler.
Thanks for backing up my initial gut feeling, Lou! I looked at lots of pics of Savi's in autumn, not having seen the species much at that season, but the head pattern of the subject bird isn't matched by any that I could find, whereas it seems typical of a Eurasian Reed Warbler.
I can see where Ken is coming from, but I don't think that the undertail coverts are as long as they might seem here. Especially as they almost seem too long for Savi's as well, if taken at face value.
Regards,
Harry

I don’t know how you can dismiss what appears to be UTC’s to the tail end, when it’s “tonal” value matches the underparts “exactly”, about as different as the surrounding reed blades as you could get.

Apologies, yes thanks for the last image, albeit one that doesn’t help to resolve the issue. Still a Savi’s for me juancar, until someone can demonstrably and unequivocally explain the “barrel” of mottled UTC’s that project to the tail tip.
On a Reed Warbler from rear of flanks to the end of...they would be contrastingly pale unlike the subject bird. :t:

That would be an “artefact” too far for me, presumably the Reed blades are also an artefact, and whilst we’re there...throw in the bird as well? :smoke:

I think the " barrel of mottled UTCs" is partly shadow, from a reed stem, especially the first broad darker area on the side flank behind the alula - the rest of the undertail coverts that we can see just dont demonstrate the pattern for me. I can see what you are pertaining to Ken, but remain unconvinced, just not sure that those longish u t coverts extend as far back as the photo suggests as its head / side on.

Sorry Roy, I just don’t see it, the underparts to my eye are too bright and continuously seamless to the tail end.
Cheers
The bird has a dark alula, which eliminates Savi's Warbler straight away.
Trying to claim anything based on the relative length/ratio of the tail/UTS'c is a moot point (and based on a single images, taken at an odd angle, and only half the tail being visible!).
Furthermore, Reed Warbler (by some margin) would be statistically be much more likely than Savi's

Isn't the tip of the tail hidden behind the reed leaf?
I think the leaf and the position of the wing is creating an illusion making it look like you are seeing the tail side-on, when you're actually seeing only the uppertail coverts and part of the upper side of the tail. Thus, trying to claim the length of the undertail coverts is not possible on this photo.
