Over the week we've caught just over 1,400 gulls, most of which were Herring Gulls, but also good numbers of Lesser Black-backed Gulls and a few other odds and sods. So below are just a few pics from the trip, perhaps useful for people to get to grips with ageing these birds.

|Fourth-summer bird or older (age code 8i): mostly adult-type primaries and secondaries, with some remnants of immature plumage|

We were lucky enough to also catch a Yellow-legged Gull; only the third we've caught on the tip. This second-summer bird can be identified by the darker grey mantle, more orange orbital ring (around the eye), a very deep long bill and a much more delineated white rump.
