Pelikan Walvis Bay

Pelecanidae is a family of large water birds that belong to the order Pelecaniformes. The family is commonly known as pelicans and is characterized by their long beak and large throat pouch used for catching prey and draining water from the scooped up contents before swallowing. They are found on all continents except Antarctica, inhabiting mainly warm regions and preferring lakes, rivers, swamps, and coastal waters.

Description[edit | edit source]

Pelicans are among the largest flying birds. They have a distinctive body shape, with a long beak and a large throat pouch. The beak can be up to 18 inches (46 cm) long in some species, and the pouch is used to catch and filter water out of the scooped up prey. Pelicans have large wings and a strong, heavy body. They are excellent fliers and can soar for long distances with minimal effort by riding thermal updrafts. Their plumage is primarily white, grey, or brown, depending on the species, with varying degrees of black on the wings.

Behavior[edit | edit source]

Pelicans are social birds and often form large flocks. They are known for their cooperative fishing technique; they work together to herd fish into shallow waters and then scoop them up with their pouches. Some species are more solitary in their feeding habits but will come together for breeding.

Breeding[edit | edit source]

Pelicans are colonial nesters, with some species nesting on the ground and others in trees or on cliffs. They lay two to three eggs, and both parents are involved in the care of the young. The chicks are altricial, meaning they are born in a helpless condition and require significant parental care.

Diet[edit | edit source]

The diet of pelicans primarily consists of fish, but they will also eat amphibians, crustaceans, and occasionally smaller birds. They feed by scooping up water and prey with their beak, then draining the water before swallowing their food.

Conservation[edit | edit source]

The status of pelican species varies from least concern to vulnerable. Threats to pelicans include habitat destruction, pollution, and entanglement in fishing gear. Conservation efforts for pelicans focus on habitat protection and reducing human-induced threats.

Species[edit | edit source]

The Pelecanidae family includes several species, such as the American White Pelican (Pelecanus erythrorhynchos), the Brown Pelican (Pelecanus occidentalis), and the Great White Pelican (Pelecanus onocrotalus), among others. Each species has its unique range, behavior, and conservation status.

In Culture[edit | edit source]

Pelicans have been featured in various cultures throughout history, often symbolizing generosity and self-sacrifice. This is due to the myth that pelicans were believed to feed their own blood to their young.
