These large birds use their elastic pouches to catch fish—though different species use it in different ways. Many pelicans fish by swimming in cooperative groups. They may form a line or a "U" shape and drive fish into shallow water by beating their wings on the surface. When fish congregate in the shallows, the pelicans simply scoop them up. The brown pelican, on the other hand, dives on fish usually a type of herring called menhaden from above and snares them in its bill.
