Aquatic or sedge warbler? (1 Viewer)

Hi,

I cannot figure out the correct ID of this little bird for a long time.
Maybe an aquatic warbler (A. paludicola) but its more likely a sedge warbler (A. schoenobaenus), I'm really unsure and don't want to miss a locally very rare Aquatic warbler.

What do you think about this bird photographed in southern Hungary ("Szeged, Fehér-tó") in the middle of September of 2014?
Habitat: wet meadow bounded by Elaeagnus angustifolia trees and very close to fishponds.

Thanks in advance for answers,
Laci

As you suspect, it is a sedge warbler!

Thanks for help, Stuart!
