Just a quick check, but a reasonable variety

SW wind drifting more westerly by the afternoon. Mainly overcast with some light showers.

Just my morning high water check of Red Nab and Saltmarsh area and Howard's check of the Heliport so far (MD)
Chiffchaff 1 near small anemometer 

Wigeon c120 initially on Red Nab then to saltmarsh and Potts corner 
Shelduck 35 out from saltmarsh 
Pale-bellied Brent 4 flew from west towards the estuary 
Little Egret 4
Grey Heron 1
Rock Pipit at least 2 - one on foreshore and one one both sides of saltmarsh 
Greenfinch 36 around saltmarsh 
Reed Bunting 2 saltmarsh 
Common Snipe 39
Jack Snipe 3 confirmed, likely there were more.
Both the above flushed as the tide covered the saltmarsh 

Heliport area:
Howard managed to read some more of the ringed Knot in the brief sunshine at high water. This one was ringed in Iceland
Knot on the Heliport wall at high water
It is very important that these Knot are not disturbed here as they
roost on spring tides, as disturbance not only prevents them being from
being read that day, but it may deter the flock from returning another day.
