A rare visitor to the state, the Mew Gull can be differentiated from similar gulls by the lack of any spots on its bill, it's yellow legs, it's rounded "petite" looking head, and its relatively small size. The name comes from the cat-like call it often gives. Mew Gulls are found across the northern Hemisphere, including races in Europe and Asia. There it is often referred to as the "Common Gull"

Habitat
Most often found around wooded lakes and rivers when on its summer breeding grounds. In winter, found along the Pacific coastline, especially near river mouths and brackish lagoons.
Diet
Omnivorous. Primary diet is often dependent upon season and location. Common food items, include fish, crustaceans, mollusks, insects, earthworms, small rodents, young birds and eggs, berries, grain, carrion, and refuse.
Behavior
Will use a wide variety of foraging techniques, including walking along the ground or in shallow water, swimming, or dipping down to the water's surface while in flight.
Breeding
Non-breeder in South Dakota. Mew Gulls are typically colonial nesters on their breeding grounds. The nest is a shallow broad cup built of grasses, and sometimes lichens, mosses, or other vegetative material. It is place on the ground, in a small tree, on a rocky ledge, or whatever traditional nesting location is found at a given location. They are the only "typical" (Larus) gull that will nest in trees. The female lays 2 to 4 eggs, with both parents helping to incubate the eggs. The young hatch after about 25 days.
Song
Repeated Kee-ya or cat-like Mee-you.

Migration
Summers throughout Northwestern Canada and Alaska. Winters along the Pacific Coast. Rarely migrates inland south of its breeding range, and is thus a rare visitor to South Dakota.

Similar Species
Somewhat similar to many other Larus gulls. Click here to look at identification keys for "typical gulls", including the Mew Gull.Key features that are characteristic of the Mew Gull (adult plumage) are as follows:
- Bill: Small, relatively thin, uniformly yellow bill without any spots at the bill tip (unlike some other Larus gulls)
- Legs: Yellow legs
- Head: Small, rounded head
- Eyes: Dark-looking eyes, with red orbital ring in breeding plumage
- Size: Small size compared to most other Larus species, particularly those commonly seen in South Dakota. Noticeably smaller than Herring Gull or California Gull, and slightly smaller than our ubiquitous Ring-billed Gull.
Conservation Status
Numbers appear to be stable throughout their normal range. They are found over a very broad geographic area, and are common to abundant in parts of that range. The IUCN considers the Mew Gull to be a species of "Least Concern".
