I saw bird nr 1 in Ras al Keimah near a water treatment plant. It is a big warbler and was not vocal at all. A rather shy bird but managed to get this shot.
Bird nr 2 was at Qudra lakes and looked even bigger than the first warbler. Very vocal and not shy at all. Bird 1 has a pinkish base to the bill and bird 2 orange. Are both Clamerous reed warblers?
Yes, both Clamorous, William. Note the short primary projection on both birds.
