Brown pelicans are found along both coasts of North America. Though once threatened by the insecticide DDT, they were one of the first species to recover from the effects and have since been removed from the Endangered Species List.

Physical Description

Males and females are similar in plumage; the head is white with a pale yellow wash on the crown; the long bill is grayish; back, rump, and tail are streaked with gray and dark brown; the breast and belly are a blackish-brown; eyes pale yellow; and legs and feet are black.

Immature pelicans have brownish-grey necks and white underparts. They will gradually acquire their adult plumage over a period of about three years. The brown pelican's most distinguishing feature is a long beak measuring approximately 9 inches (23 centimeters) in length with a hooked tip and large pouch beneath. The huge naked skin pouch suspended from the lower half of the hooked bill holds two or three times more than the bird's stomachabout one gallon of water and fish. Pelicans hold their catch and let the water drain from the corners of their mouths before they swallow. Fish are never carried in the pouch, but in the gullet or esophagus. The pouch is also pulsated in extreme heat to allow cooling.

In flight, brown pelicans are easily identified by a pattern of a few flaps followed by gliding.


Brown pelicans are the smallest species of pelican. Both males and females are 3 to 5 feet (0.9 to 1.5 meters) long and weigh over 7 pounds (3 kilograms).

Native Habitat

Of the seven or eight species of pelican, the brown pelican (also called the American brown pelican or common pelican) can be found from Virginia, south to the mouth of the Amazon River in Brazil, from central California to south-central Chile and the Galapagos Islands, and in Alabama, Louisiana and Texas along the Gulf Coast.


Adult brown pelicans make very few vocalizations. Occasionally, they will make a low croak. Nestlings squeal.

Food/Eating Habits

Brown pelicans use their pouch, swimming ability, and extremely keen eyesight to catch fish. Flying over the ocean, they can spot a school of small fish from heights of 60 to 100 feet (30 m). After spotting the fish, the pelican folds back its wings and dives deep into the water, submerging completely or partially before emerging with a mouthful of fish. Air sacs beneath the pelican's skin cushion the impact and help it resurface.

Brown pelicans are the only species of pelican that hunts with such dramatic plunging dives. Other pelican species fish by swimming on the surface of the water, which is also a method sometimes used by juvenile brown pelicans. Their pouch, which they use as a dip net, holds the catch of fish until the water (as much as 3 gallons) is squeezed out. The pouch itself can hold three times more fish than the stomach. While fish is being held in the pouch, gulls often hover above or even sit on the pelican's bill ready to steal a fish or two. Once the water has drained from the pouch, the pelican swallows the fish. The pouch also serves as a cooling mechanism and as a feeding trough for young pelicans.

Brown pelicans feed on mid-sized fish and some invertebrates. They require up to 4 pounds of food per day. Their diet consists mainly of menhaden, herring, sheepshead, pigfish, mullet, grass minnows, top minnows and silversides—all fish considered commercially unimportant.The brown pelicans' diet at the Smithsonian's National Zoo consists of thread herring. They are also given vitamin supplements based on the amount of fish they eat.

Social Structure

Pelicans are social and gregarious. Males and females, juveniles and adults, congregate in large flocks for much of the year. In level flight, pelicans fly in groups, with their heads held back on their shoulders, the bills resting on their folded necks. They may fly in a "V," but usually in regular lines or single file.

Conservation Efforts

The brown pelican has few natural enemies. Flooding or hurricanes sometimes destroy ground nests, but the biggest threat comes from humans. In the late 19th and 20th centuries, pelicans were hunted for their feathers to adorn women's clothing and hats. During the food shortages of World War I, fisherman claimed that pelicans were depleting resources from the commercial fishing industry and slaughtered them by the thousands. Their nests were also frequently raided for eggs.

In the 1940s, the pesticide DDT began to be widely used and cause a decline in the pelican population due to eggshell thinning. In 1903, President Roosevelt designated Florida's Pelican Island as the first national wildlife refuge, which helped to reduce the killing of pelicans for their feathers. In addition, passage of the Migratory Bird Treaty Act in 1918 gave protection to pelicans and other birds. Studies proved that pelicans were not harming the commercial fishing industry, which helped to stop the killing of pelicans by fishermen.

In 1970, the U.S. Fish and Wildlife Service listed the brown pelican as an endangered species meaning that it was considered in danger of extinction through all or a significant part of its range.

In 1972, the Environmental Protection Agency banned the use of DDT in the U.S. and placed heavy restrictions on the use of other pesticides. Since the banning of DDT, there has been an increase in nesting success. The brown pelican was the first bird species to recover from the effects of pesticides.

In November 2009, the brown pelican was de-listed and removed from the Endangered Species list.

Today, abandoned fishing lines, other marine debris, and overhead wires still pose a threat to the brown pelican. In Florida, at least 500 pelicans are killed each year from entanglement in fishing gear. The brown pelicans on American Trail are rehabilitated birds, injured in this fashion.
