White pelicans are among the largest Mississippi Flyway migrants. At an average weight of 16 pounds (7 kilograms), they rely on a nine-foot (three-meter) wingspan to enable flight at very high altitudes. They use a unique fishing technique, cooperatively herding fish into small areas on the surface where the pickings are easy.
