Mediterranean Gull (L. melanocephalus)
Mediterranean Gull 7cy 3P07 March 08 2008, Le Portel / Boulogne-sur-Mer, NW France. Picture: Jean-Michel Sauvage.
Bird from Belgium. Ringed as pullus on 26 May 2002 at Zandvlietsluis colony, Antwerpen, BELGIUM. It was trapped again to receive ring white 3P07 on 13 May 2006, again at Zandvlietsluis.
From June to September, a complete moult takes place, into so-called "adult winter" plumage. The head pattern resembles the pattern in first winter birds, with blackish mask behind the eye. The mantle, scapulars, tertials and all the wing-coverts are replaced for plain pearl-grey feathers. The secondaries are completely white. The adult primaries are shiny pearly-grey, flashing white at a distance. There is a black line along the outer-web of P10 (and sometimes on P9 as well). Secondaries, under-wing and tail all completely white. The bare part coloration in adult plumage: Iris brown, orbital ring red or orangey-red, the bill red or orangey-red with a black bill-band and a yellowish tip and the legs dull reddish or dark. There is some variation in 3cy and 4cy wing-tip patterns.
The next moult in Mediterranean Gull is again a partial moult, from December to March-April and includes body and head, leaving birds in so-called "adult summer" plumage. The head develops a jet-black hood, extending down the nape. Adult birds have broad and contrasting white crescents above and below the eye. The bare part coloration in adult plumage: Iris brown, orbital ring coral red, the bill scarlet red often with a thin black bill-band and a yellowish tip and the legs red.
