These Iceland Gulls were digiscoped on the Toronto, Ontario, waterfront of Lake Ontario during the winter of 2003 using a Nikon Coolpix 4500 camera and a Swarovski ST-80HD telescope with 20 x 60 zoom telescope. The variation in wingtip coloration and pattern ranges from white with no pigmentation to blackish with mirrors.
