Lesser Black-backed Gull (graellsii) 2nd cycle (3CY), April 28 2012, Belfast, N Ireland. Picture Graham Ekins.

Classic "grey saddle". 2nd gen flight feathers, except for one pair of rectrices replaced on winter grounds. Several wing-coverts and the upper tertials included in the partial autumn moult, now more adult-like than other coverts.
