The pelican, for instance, has a pouch that hangs down from the underside of its long beak. The pouch is the bird’s ‘fishing net’ and can expand to hold several fish at a time.

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. Pelicans do not store fish in their pouch, but simply use it to catch them and then tip it back to drain out water and swallow the fish immediately. The American white pelican can hold some 3 gallons of water in its bill. Young pelicans feed by sticking their bills into their parents' throats to retrieve food.
