Rain on & off all morning. 1,815 Cormorants went out fishing. Noticeable movement of Herring Gulls heading south in small groups with 432 logged - the reason behind this is difficult to explain. Also southbound 15 Great Black-backed Gull, 13 Shelduck, 7 Brent & 7 Red-throated Diver with northbound Great-crested Grebe & Red-throat plus 2 Great-crests sat on the sea. A Purple Sand was on the jetty & a Ringed Plover was displaying in song flight over the reserve.
