This morning two Water Rails feeding in the mud and reed fringes in front of South hide, occassionally squabbling.  Slavonian Grebe showed really well just beyond Cormorant post in front of the hide, frequently diving and surfacing once with a small fish. Later there were 2 Slav. Grebes, almost displaying (?) with some head bobbing and mirroring of movements.  Vocal Cetti’s zipped across the right hand cut.
