Was looking at a group of Common gulls ( S-Iceland ) . One of them first winters stood out as having much paler head and much longer bill .It also looked to much less progressed in moult , only part of mantle feathers changed while other first years had changed both mantle and scapulars . Is it a freak or a sp.of c.... . Sorry for bad quality pics . In one pic the most left bird and in the other behind HG.
