|Adult Herring Gull (note the yellow legs), Colour-Ringed in Finland C02CN|
The A5 Lagoons are a bit hit and miss these days, due to disturbance from various creatures including a man who walks round the edge of the lagoons fairly regularly. I haven't caught up with him for a chat yet, but I will. As a consequence I have been devoting most of my time to watching the gulls at the sand quarry next to Cotesbach Landfill site. The good thing there is that all the gulls have there legs out of the water. As a result I get to read more colour-rings.
There are at least seven Caspian Gulls around at present: three adults, one 4CY, two 3CY, one 2CY and one 1CY. The 1CY was seen by Martin Elliot, but I can see from his photo that I saw it in both September and October.
The 2CY in the video below showed very well this afternoon. The video doesn't do it full justice as the lovely silver grey of the mantle and the median coverts has lost something. Nevertheless it shows how distinctive the body shape is compared to the nearby Herring Gull.
