"This guide is intended to help users differentiate between five species of gulls common to Canada’s eastern provinces, specifically those with habitats located near human activity. Gulls can be difficult to identify, as the characteristics used to distinguish between species are often not noticeable, and can vary within a given species from season to season and by age. This guide contains brief descriptions of the following five species: Herring Gull (Larus argentatus), Great Black-backed Gull (L. marinus), Ring-billed Gull (L. delawarensis), Glaucous Gull (L. hyperboreus), and Iceland Gull (L. glaucoides).
