Great Black-backed Gull (Larus marinus) 3cy: February 09 2003, Boulogne/Mer, N France.

The lower scapulars and single coverts are rather plain dark grey. All other coverts show the common pattern for second generation feathers: broad bars which are connected with each other by a clear shaft streak. Note the small white tips on the primaries.
