Iceland and Glaucous Gulls are scarce winter visitors to the UK. They often occur singly amidst groups of commoner species like Common Gulls, Herring Gulls and Lesser and Great Black-backed Gulls, when different age plumages, mixed-species flocks and poor light conditions can make identification tricky. 

Our identification video will help you learn the key features of both species so you can pick out these so-called 'white-winged' gulls with confidence.
