The Corse now holding lots of water, so a good couple of hours in the hide. A female marsh harrier (visibility too poor for detail) cruised briefly up and down, putting up lots of mallard and teal from the reedbed. At least 6 moorhen, several water rail and 2 little grebe, one of which caught an actual fish in front of the hide, 2 little egrets and a grey heron. A great spotted woodpecker was a surprise. Lots of small birds for BirdTrack, the bramble patch in front of the hide this morning featuring a chiffchaff.
