Kumlien's Gull (kumlieni) adult, January 25 2012. Saginaw River, Michigan. Pictures: Dan Duso.

This bird has an especially dark eye. Image 2 provides a comparison with Herring Gull. This would be a "Stage 4" bird, with darker grey or more extensive grey marks on the outer five primaries with complete subterminal bands on zero to three primaries. This stage 4 was scored in 55% of the adult Kumlien's at Newfoundland in the research by Howell & Mactavish. For explanation, see chart.
