Acrocephalus ID, Bulgaria (1 Viewer)

[Pavel]

Hi,
Help me pls. ID this Warbler, photo taken today, 17/04/2021 at Lake Durankulak, NE Bulgaria.
Looks like Marsh W. but strange pale neck collar and pale rump as well.
Thanks for your comments.

too much buffish tones on flanks, bill curved downwards, worn remiges - looks like an Acrocephalus scirpaceus to me. it would be extremely early for marsh warbler. and a marsh warbler should have a very fresh plumage and yellowish tones on underparts.

Thanks Lou, also pale legs but I agree probably some variations, what about this pale neck collar?
