Shortly after a very heavy shower at 11.18 I started to count whimbrel. At about 450 I realised I was looking at 3 black-winged stilts. I forgot to count the remaining whimbrel. After another very heavy shower I was unable to re-locate them. They were near the canal-side car park.
Also c20 swifts, 1 probable little-ringed plover and hundreds of whimbrel. Also c45 geese flew over , probably brents - pale bellied.
