Common Gull

1st winter Common Gull, Milton, 29th January 2007, © Dick Newell
Most nominate canus Common Gulls should have moulted their scapulars by late September but this bird has barely started. This is more typical of birds from a more northerly or easterly origin. Together with the primaries hanging below the tertials and inner greater coverts this bird could be heinei. See this Danish example of a November heinei. (RGN)
