Caspian Gull
 

Larus cachinnans

Above: Probably 4th winter/5th calendar year (Essex, 10 February 2012)

The light conditions late in the afternoon with a very low dusky sun would appear to have caused the grey upperparts of this individual to look particularly dark. It would be interesting to see the exact tone of the greys in flat daylight. There's a touch of barabensis about this bird!
