Yellow-legged Gull

Yellow-legged Gull, adult and 2CY, Smithy Fen, Cottenham, 12th September 2008, © Dick Newell
The adult bird, in active primary moult, demonstrates nicely the characteristic head-shape of many Yellow-legged Gulls. The 2CY bird has mostly second generation feathers apart from a few 3rd generation grey mantle feathers. Most 2CY Yellow-legged Gulls would have a lot more grey on the back by this date. This bird had a yellowish tinge to the legs, which is not always the case at this age.
