This gull was sitting on a groyne off of Yarmouth today. From the RSPB website: - A large pale gull with white wing tips. Younger birds are creamy white or more biscuit coloured, depending on age. All have pale wingtips. It is bigger than a herring gull and bulkier, with a fiercer expression, larger beak and squarer head than the smaller but virually identically-plumaged plumaged Iceland gull.
