With its wingspread of six or seven feet and light body, weighing between five to eight pounds, Brown Pelicans are built to soar and search wide areas of the Gulf of Mexico for fish.
They can fly up to 35 miles per hour if the winds are cooperating. As it reaches the water, it will fold the wings back further and extend the beak. Once it hits the water, the beak will be open and its pouch will automatically stretch to capacity, filling with water and the small fish it was aiming for — some fish will be in its pouch and others will be stunned, which the pelican quickly scoops up with its long beak and pouch, just like a net.
The throat pouch can hold up to three gallons of water and fish, about twice the capacity of its stomach. Water is drained from its bill at the sides of the mouth. If the fish are not eaten on the spot, the fish are never carried in the pouch, rather in the gullet. The decline of the local Brown Pelican population documented from through today by Ted Below, tells the tale of environmental impacts such as storms and global warming to direct human impacts such as habitat loss, food supply decline, oil spills, feeding pelicans and fishing line and trash in the environment.
When roosting and nesting habitats are destroyed or removed by storms, development or pollution, impacts to population are negative. Removing or over trimming mangroves is a double edged sword to a Brown Pelican — roosting and nesting sites disappear as well as the habitat that is needed to produce its diet — fish.

The Australian Pelican may feed alone, but more often feeds as a cooperative group. Sometimes these groups are quite large. One group numbered over 1, birds. A flock of pelicans works together, driving fish into a concentrated mass using their bills and sometimes by beating their wings. The fish are herded into shallow water or surrounded in ever decreasing circles.
Breeding depends on environmental conditions, particularly rainfall. Pelicans are colonial breeders with up to 40 individuals grouping on islands or secluded shores. Breeding begins with courtship. The female leads potential mates two to eight or more around the colony. As the males follow her in these walks, they threaten each other while swinging their open bills from side to side trying to attract the female's attention.
The males may also pick up small objects, like sticks or dry fish, which they toss in the air and catch again, repeating the sequence several times. As the courtship parade progresses, the males drop out one by one. Finally, after pursuits on land, water or in the air, only a single male is left. The female leads him to a potential nest site.
During the courtship period, the bill and pouch of the birds change colour dramatically. The forward half of the pouch becomes bright salmon pink, while the skin of the pouch in the throat region turns chrome yellow. Parts of the top and base of the bill change to cobalt blue, and a black diagonal strip appears from the base to the tip.
This colour change is of short duration, the intensity usually subsiding by the time incubation starts. The nest consists of a scrape in the ground prepared by the female. She digs the scrape with her bill and feet, and lines it with any scraps of vegetation or feathers within reach of the nest. Within three days egg-laying begins and eggs are laid two to three days apart.
Both parents share incubation and the eggs are incubated on their feet. The first-hatched chick is substantially larger than its siblings.
It receives most of the food and may even attack and kill its nest mates. A newly hatched pelican has a large bill, bulging eyes, and skin that looks like small-grained bubble plastic. The skin around the face is mottled with varying degrees of black and the colour of the eyes varies from white to dark brown.
