A Kumliens Gull without grey tips to the primaries is in fact er em an Iceland Gull! Well yes and no!! Some Kumliens Gulls in Newfoundland have no grey on primaries but however they are darker mantled than Iceland Gulls er em like this bird at Killybegs. So i think this is a pale winged Kumliens Gull however i cant prove it without shooting it. Cest La Vie!
