Despite the fact that pelicans are omnivorous birds, pelicans mainly feed on fish, crustaceans such as prawns and crabs, small species of turtle and squid. The pelican uses it's beak pouch to scoop a mouth-full of water up and then strains the water out of it's beak leaving the food (such as fish) behind for the pelican to eat.
During the breeding season, pelicans nest in colonies and breeding usually begins with a group of male pelicans chasing a single female pelican. The pelican courtship can occur on land, in the air or on water. The male pelican collects materials to build the nest which the female pelican then uses to build the nest either on the ground or in a tree depending on the pelican species.
The female pelican lays an average clutch size of 2 eggs which both the female pelican and the male pelican help to incubate. After an incubation period of around a month, the pelican chicks hatch out of their eggs but often, only one pelican chick will survive out of the two. The female pelican feeds her young until they are around 3 months old, although baby pelicans are usually able to walk and swim when they are about 2 months old.
Due to their generally large size, pelicans have few predators in their natural environment. Wild dogs such as coyotes are one of the main predators of the pelican along with cats and humans who hunt the pelican for their meat and feathers.
Pelicans inhabit areas around the world usually in large flocks of more than 100 birds. Pelicans rest and nest together in these communities but often hunt and feed alone with the exception of the female pelican feeding her pelican chicks. The pelican chicks are known to gather together in small groups within the communial nesting site of their parents.
