Caspian Gull |

Larus cachinnans Above: Juvenile-1st winter/1st calendar year (Essex, 10 September 2010) Unfortunately, we never got to see the greater coverts on this well-marked bird as it remained partially obscured the whole time we were able to watch it. The lesser and median coverts appear to be rather strikingly patterned.
