While we were waiting for the Gulls to feed over the catching area at Pitsea tip yesterday. I had a go at trying to get some flight shots of the Med Gulls. In the first shot below, you can just see a faint pencil line on the outer web of its primary. Something that you can't always see when out in the field but up close its just visible. The same goes with its bill, all photos show a deep red bill but up close its got a pale yellowish tip. That's why I enjoy Gull ringing ,you get the chance to see all gulls finer detail. Where maybe you can't see or miss when your out birding!
