This evening the Starling roost was really spectacular as about 8,500 birds came in to roost. Hundreds of corvids were flying across the site and then about 1,500 Canada and Grey-lag Geese arrived en mass on the Slurry Lagoon.  As this was all going on a juvenile Swallow came in from the north and circled the lagoon a few times, as if making up its mind whether to join the Starlings or not, but then flew off to the north. A Sparrowhawk was seen three times trying to catch a Starling from the roost and a Water Rail flew across the gap in the reeds in front of the Causeway bench. PS.
