Gulls

species:

Lesser Black-backed Gull

scientific name:

Larus fuscus

notes:

Green ring with a white two alpha code (on left tibia).

note 1 : all rings are of the same design, with the letter repeated round the ring, so that the letters read horizontally on a standing bird. See image.

note 2 : birds are ringed as breeding adults on Skomer Island, Wales, as part of long-term population monitoring dating back to the 1970s

note 3 : Only the 20 letters A, B, C , D, F, H, I, J, K, L, N, O, P, S, T, U, V, X, Y, Z are used, since the others are too large (W , M) or too likely to other letters (E, G, Q, R).
