Relatively few gull species are common nesters in the Lower 48. But in October, both the variety and number of gulls increase dramatically. Gulls that nested in Alaska or Canada fly south to spend winter in more temperate climates. Western Gulls are present in the West all year, mostly near the coast. Mew Gulls turn up in the winter along the West Coast, and Herring Gulls can be seen in the East. October is an ideal time to learn which gull is which. Seen here, top to bottom, are Western, Thayer's, and Glaucous-wing Gulls.
