American Avocets wade through shallow water to catch aquatic insects. They also consume aquatic vegetation and seeds. They will consume beetles, shrimp, small fish, and many other kinds of aquatic invertebrates. Their unique upturned bill helps them catch their prey by moving their bill side to side as they wade through the water.
American Avocets usually nest on open flats or areas with scattered tufts of grass on islands or along lakes, including alkaline, and marshes. Readily nests on artificial islands in impoundments. Males and females both aid in choosing a nest site and constructing the simple ground nest by scraping the ground. The female lays 3-4 eggs and a couple hours after hatching the long-legged chicks are able to scamper around.
