Characteristics of Pelicans
Pelicans are known for their distinctive physical traits and their remarkable behaviors relating to habitat, feeding, and flying.
These birds are easily recognized by their large bodies, elongated bills, and expansive throat pouches, adapted for an aquatic life of expert fishing.
Physical Description
Pelicans are an exceptional group of large water birds characterized by a striking bill and a throat pouch.
The American White Pelican and Brown Pelican are prime examples of this family.
The former often boasts a predominantly white plumage, while the latter typically presents a brown coloration.
Both species have a wingspan that is notably broad, aiding in their impressive flight capabilities.
Adult pelicans can reach a considerable size, with body length varying across species, and some individuals measuring up to 70 inches.
Their throat pouch is not only expandable but also vividly colored, often displaying a yellow hue that contrasts with their plumage.
Habitat and Distribution
The habitats of pelicans range from lakes to sea environments, where they prefer coastal areas, islands, and inland waters.
They are widely distributed over the globe with the American White Pelican found in areas like Western Canada and throughout North America, including regions such as California, Texas, and Florida.
The Brown Pelican is common along the Pacific coast, and both species are migratory, moving to the southeast, southwest, and the northwest according to the breeding season.
They often favor warm regions but can be seen as far north as the Spanish flu impacted areas during migration times.
Feeding Behavior
Pelicans primarily feed on fish, and their feeding techniques are as remarkable as their physical characteristics.
The Brown Pelican is known to dive from the air, plunging into the water to catch fish like menhaden and herring.
Contrarily, the American White Pelican does not dive but forages cooperatively by forming groups that move in unison to corral fish in shallow water before scooping them up with their pouch.
Overall, their fishing methods differ, but both are highly effective at exploiting their respective habitats for food.
Despite their size, pelicans are agile as they fly in formations and swim with ease, highlighting another layer of their diversified abilities in capturing prey.

Conservation and Life Cycle
The life cycle of pelicans is closely intertwined with their conservation.
Understanding their breeding patterns, the threats they face, and their migration habits are essential for ensuring their survival.
Reproduction and Breeding
Pelicans are colonial nesters, with both sexes collaborating in the creation of the nest.
The breeding season sees a significant increase in activity as they establish colonies on coastlines, islands, or inland waterways.
A pelican’s nest, often a scrape in the ground or a more elaborate structure if on a tree, becomes a hub of activity where eggs are laid and vigilant parents rear their young.
Typically, a brown pelican clutch comprises two to three eggs with incubation lasting around 30 days.
Threats and Conservation
Historically, pelicans have been threatened by pesticides like DDT that weakened eggshells.
Conservation efforts, including the ban of such harmful substances, have enabled pelican populations to rebound, improving their conservation status.
However, they continue to face threats from oil spills, fishing gear entanglements, and habitat loss.
Vigilant conservation practices are crucial for pelicans, especially during the sensitive breeding season, to prevent them from becoming endangered once more.
Migration Patterns
Migration is a remarkable feature of pelican life.
While white pelicans often travel in impressive flocks, soaring in V-formations or lines, brown pelicans are less consistently migratory, depending on their geographic location.
Inland rivers can serve as migratory pathways.
Some populations migrate to warmer regions during winter, while others in milder climates may not migrate at all.
The sight of pelicans in flight, whether migrating or simply moving between feeding grounds, is a testament to their endurance and the majestic capability for long-distance flight.
