Overview of the American White Pelican
The American White Pelican is a magnificent bird species that can be found in the United States, including in the state of Oklahoma. Despite the common misconception that pelicans are exclusively ocean birds, these unique and majestic creatures can also be spotted near large freshwater lakes or shallow wetlands in Oklahoma. This article will provide a comprehensive overview of the American White Pelican, including its physical characteristics, habitat and distribution, feeding behavior, reproductive behavior, and flight patterns.
Physical characteristics
The American White Pelican is known for its giant size and striking appearance. These pelicans are significantly larger than their cousin, the brown pelican, weighing between 11 and 20 pounds (5.0 – 9.1 kg). However, it is their impressive wingspan that truly sets them apart. When fully spread, their wings measure over 9 feet (2.7 m) from tip to tip, making them one of the largest wingspans among North American birds. They have a long neck and bill, with a yellow patch at the base of the bill that wraps around their eyes. Breeding adults also have a unique protruding plate on the bill, adding to their distinctive features.
Habitat and distribution
American White Pelicans can be found in various regions of the United States, including Oklahoma. They are typically found near large freshwater lakes or shallow wetlands, where they can easily find an abundance of fish. During migration, they may also be seen in other areas, as they travel to and from their nesting grounds. In Oklahoma, these pelicans are most commonly observed during spring or fall migration.
Feeding behavior
Unlike their brown pelican relatives, American White Pelicans do not dive into the water to catch fish. Instead, they use their large neck pouches to scoop up fish while swimming. They can often be seen bobbing their heads underwater, searching for prey. Interestingly, these pelicans often engage in collaborative hunting strategies, working together to herd fish into shallow areas where they are easier to catch. This cooperative behavior makes their feeding habits even more fascinating to observe.
Reproductive behavior
The reproductive behavior of American White Pelicans is equally intriguing. While still inside the egg, the chicks can communicate with their parents by squawking if the conditions become too hot or too cold. This early communication is essential for the survival of the chicks. Once hatched, the chicks rely on their parents for food and protection. Adult pelicans are generally silent, but they may make vocalizations during courtship or if they feel threatened. Their nesting habits vary depending on the location, but they tend to build their nests in colonies, often on islands or inaccessible areas to protect their young.
Flight patterns
When in flight, American White Pelicans are a sight to behold. Their wide wingspans allow them to soar gracefully through the sky for long distances. It is not uncommon to see them flying in a V-formation, which not only enhances their aerodynamics but also creates a mesmerizing spectacle. The sight of a flock of American White Pelicans flying in formation is reminiscent of prehistoric birds and captivates the attention of onlookers.

Collaborative hunting strategies
American White Pelicans often exhibit collaborative hunting strategies, working together to herd fish into shallow areas. By doing this, they make it easier to catch their prey. This cooperative behavior is fascinating to witness and showcases the intelligence and social nature of these birds.
Reproductive behavior
Chick communication while still in the egg
One of the most intriguing aspects of American White Pelican reproduction is the communication that occurs between the chicks and their parents while the chicks are still inside the egg. If the temperature becomes too hot or too cold, the chicks can communicate their discomfort by squawking. This communication allows the parents to adjust their behavior and provide the ideal conditions for the unhatched chicks.
Adult vocalizations
While adult American White Pelicans are generally silent, they may make vocalizations during courtship or if they feel threatened. These vocalizations can vary in intensity and pitch, serving as a means of communication within their social groups.
Nesting habits
American White Pelicans typically nest in colonies, often on islands or other inaccessible areas. By choosing these locations, they can protect their nests and young from predators. Their nesting habits vary depending on the specific location, but they generally build nests on the ground using materials such as sticks, vegetation, and debris.
Flight patterns
Impressive wingspan
American White Pelicans are known for their impressive wingspan, which measures over 9 feet (2.7 m) from tip to tip when fully spread. This wide wingspan allows them to glide effortlessly through the air and soar for long distances with minimal effort.
Graceful soaring
When in flight, American White Pelicans display a graceful soaring behavior. They effortlessly ride air currents and utilize their broad wings to maintain stability and conserve energy. Witnessing them soar through the sky is a remarkable sight that showcases their aerial prowess.
