Ringed as pullus on July 09 1988 at518 Langenesveien, Søgne, Vest-Agder, Norway (58° 1' 59N, 7° 55' 0E). Primary moult score (PMS) of 39, with the outer primaries P9-P10 still old. P9 lacks a mirror. Moult will progress at a very low pace or will be suspended until arrival at the wintering grounds. Compare the grey tone of the upper-parts with the Herring Gulls. This is a rather elongated bird (cachinnans-like) with a longer neck and attenuated rear end, unlike the more compact canus-like individuals in the other images. It's a dark grey individual with the head-streaking concentrated in the lower hind-neck, on the crown and around the eye. |
