American White Pelicans Feeding Behavior

The American White Pelican (Pelecanus erythrorhynchos) is one of two species of pelican in North America, along with the Brown Pelican (Pelecanus occidentalis). While occasionally seen in the same locations, American White Pelicans and Brown Pelicans prefer different habitats and their manner of feeding is as different as their plumage.

American White Pelicans are large, mostly white birds. Their primary and secondary feathers are black. In breeding season adults develop a yellow crest. Juvenile birds can be distinguished by a brown wash on the head, neck and wings. Non-breeding adults have yellow bills, which turn more orange and grow a vertical fibrous plate on the maxilla (aka upper mandible) for breeding. The plate is shed after the eggs have been laid. American White Pelicans are generally found on fresh water rivers, lakes, and ponds, though they also inhabit saline bodies of water inland such as the Salton Sea, Mono Lake, and the Great Salt Lake. They are found along the Pacific and Gulf coasts in the winter, and migrate inland to the Rocky Mountains in the US and Canada to breed and fledge young. American White Pelicans are social birds and are often found in large flocks roosting on beaches and islands or fishing cooperatively by herding schools of fish into a confined area. Contrary to the famous limerick by Dixon Lanier Merritt,

A wonderful bird is the pelican,
His bill will hold more than his belican,
He can take in his beak
Enough food for a week
But I’m damned if I see how the helican!

pelicans do not use their beaks for storing food. American White Pelicans feed by floating along, sticking their heads under water to find their prey, and then scooping the fish up in their bills. In contrast, Brown Pelicans will dive into the water to grab their target fish. Herding was not necessary for these three birds as they fed in a pond that was well stocked with fish. Nearly every attempt resulted in success.

The three American White Pelicans in the video illustrate how graceful these large bird can be on the water. They are just as graceful in the air. It is always a stunning sight to see a large flock in migration as they lift off of the water and use thermal updrafts to circle and climb thousands of feet to clear a range of mountains on their springtime northern push.

The video was recorded on a micro 4/3 camera connected to a Kowa TSN-884 spotting scope with TE-11WZ eyepiece by means of a Kowa TSN-DA10 adapter.
