Did the gull roost with Warren Claydon and amongst the biggest roost of the Winter.
Warren spotted a 3rd W ICELAND GULL on the BBOWT Lake. It has white primaries, very light grey mantle, small amount retained immature plumage and dull yellow bill; viewed at very long range. At least one adult CASPIAN GULL still present.We
We looked for the Iceland on main sailing roost but couldn't spot it amongst the huge roost in bad light.
Also redhead GOOSANDER, 1-2 BITTERNS seen in flight and BLACK-NECKED GREBE still on sailing lake by reedbed on East bank (per Tim Watts)
