The white pelican is one of the most successful fish-eating birds. The success is in largely due to its command hunting behavior. A group, perhaps to dozen birds, will gather in a curved arc some distance offshore. The bird than begin to move forward towards to shore, beating the water furiously with their wings, driving the fish before them.
When the water is shallow enough for the birds to reach the fish, the formation breaks up as each birds dips its bill into the water to scoop up its meal. As the bird lifts its head, the water drains from its bill leaving the fish which are then swallowed.
Pelicans are among the oldest group of the birds. Fossils of this genus have been found dating back 40 million years.
