Great Black-backed Gull (Larus marinus) 2cy: February 04 2002, IJmuiden, the Netherlands (52.27 N, 4.33 E).

Note the juvenile wing-coverts and tertials. The recently moulted second generation scapulars show an anchor pattern, a broad white fringe and a 'ginger'-coloured base. Some scapulars were moulted quite a while ago and show wear in the fringes.
