More Variation in Iceland and Kumlien's Gulls

Bluffers Park in Toronto

This Iceland Gull was at Bluffer's Park in east end Toronto on1 February 2015. It had immaculate white primaries, its mantle was much paler than the Ring-billed Gulls, and it had very pale eyes. Ron Pittaway and I watched it in flight and its primary tips were immaculate, though I have no flight shots. We consider it a pure Iceland Gull Larus glaucoides glaucoides which breed in Greenland because it shows no characters of a Kumlien's Gull.
