Juvenile: Pitsea Tip, Essex - July 2009

Note the tail pattern: the tail is mostly white with a broad dark brown narrowly white tipped band with a series of narrow dark bands up to the feather bases. The upper-tail coverts are pale brownish.

There is a distinct pale window on the inner primaries which is almost as prominent as on Herring Gull however note the greater covert pattern which becomes progressively more solidly dark towards the outer feathers. Compare with juvenile Yellow-legged Gull by clicking here.
