FUN FACTS

1. Brown pelicans are the only species to dive into the water from 30 feet above to capture prey. After catching the prey and a lot of water, they tip their bill downward to drain the water before swallowing the fish.
2. While brown pelicans are known for diving, they will never be deep divers due to the extensive system of subcutaneous air-sacs that give them theirbuoyancy in the water.
3. The pelican's pouch (gular pouch) is used as a dip net to catch fish, which are soon swallowed into the stomach (the center of gravity) so that they can maintain their balance while flying.
4. They have an extendable sac of skin at the base of their throat, which is capable of holding up to 3 gallons of water, several times more than their belly.
5. Most fossil species of pelican are placed in the same genus as the modern pelican due to extreme anatomical similarities. This suggests that the present form of pelican has changed very little over the past 30-40 million years.
6. The brown pelican, the smallest of the Pelecanidae family, can fly up to 30 mph.
7. Its gular pouch may be used to disperse heat as well as to collect fish and rainwater.
8. Brown pelicans are best adapted to living alongside humans. They are frequently seen at fishing ports up and down the coast, opportunistically feeding on fish scraps discarded by fisherman.

ECOLOGY AND CONSERVATION

Pelicans have attracted human attention for centuries. Their images are widely used as caricatures for commercial enterprises such as hotels, restaurants, toys, and books.

They are primarily birds of warm climates and breed mainly in isolated areas away from predation and human disturbance. Pelicans require large quantities of food daily. Food supply is often a limiting factor in pelican distribution and range. Fortunately, pelicans feed mainly on "trash" fish that have little to no commercial or sporting value. Nevertheless, pelicans are often victims of fishing hooks and lines, oil spills, pesticides, guns, arrows, cars, boats, and power lines.
