My first post so I’m looking for help to ID gulls. Then I find gulls change with age and season. This is a challenge. In late September this year at Regina Beach on a freezing cold day we managed the outdoors to get some pictures. What drew my attention first of all were these 2 large dark brown gulls. Because they were cold too (I’m sure) kept tucking their bills in. Could they be Western Gulls? We have American White Pelicans, Double-crested Cormorants, Caspian Tern, Herring Gull, another tern. Could there be an Iceland Gull? Any pointers to help in ID?
