As the light dimmed, at about 16.15, the Starlings began to arrive to roost. A group of about 1,000 formed and did an aerial display, then decided to have a mass bathe amongst the gull roost. Another group of about 1,000 arrived and then both groups amalgamated and smoked into the reed bed. Then lots of smaller groups of fifty to 200 birds arrived, mostly from the east and dived spectacularly into  the reed beds to join the others. This carried on for about thirty minutes until I estimated about 4,500 birds were in the roost. Whilst this was happening there were echelons of  Grey-lag and Canada Geese arriving to roost on the Large Gravel Pit and the numbers grew to about 1,200 Grey-lag and about 800 Canadas. On the Slurry Lagoon the gull roost reached in excess of 1,000 birds but the light did not make counting them practical. A Water Rail flew across the gap in the reed beds in front of the bench and the Cetti’s was in good voice. PS.
