An interesting Iceland Gull

This bird was present at Peterhead on Saturday. It shows a contrast between extremely worn outer and fresh inner primaries.

It is clear from this and the images below that the bird has suspended its primary moult. Its secondaries are also unusual, with a mixture of fresh (presumably moulted in in the autumn) and extremely abraded (retained) and missing feathers.
