Sanderlings (Calidris alba) run back and forth on the beach near the wave line looking for small invertebrate marine life to feed upon. They move very quickly and tend to move about as flocks. They are also called sandpipers. They have black bills, gray backs and white bellies. They breed in the Artic but migrate south to the warmer climates during winter. They are a common sight on Florida’s beaches. I caught this flock on a Sanibel beach and they were also pretty to look at as they were flying. The Cornell Lab of Ornithology “All About Birds” website has some excellent information about Sanderlings and other birds.
