24 March Photos: Swan Lake Gulls March 6, 2011March 24, 2008 by matt goff This entry is part 46 of 143 in the series 2008 Photojournal [Show slideshow] Thayer's Gull (Larus thayeri) and Glaucous-winged Gull (Larus glaucescens) at Swan Lake. I think this is a female Glaucous-winged Gull (Larus glaucescens) due to its relatively small size.
