Pelicans are a group of large, waterbird species that are found on every continent except Antarctica. They are known for their large, distinctive bills, which they use to catch and filter fish and other aquatic prey. There are eight species of pelicans, which are found in a variety of habitats including wetlands, rivers, and coastal areas.
Pelicans are generally large birds, ranging in size from the brown pelican (Pelecanus occidentalis), which is about 1 meter (3.3 feet) tall and has a wingspan of up to 2.5 meters (8 feet), to the Dalmatian pelican (Pelecanus crispus), which is up to 1.5 meters (5 feet) tall and has a wingspan of up to 3.5 meters (11.5 feet). Pelicans have long, thin legs and a large, pouched bill, and they are often found standing on one leg.
Pelicans are carnivorous, feeding on a variety of aquatic prey including fish, amphibians, and invertebrates. They are known for their elaborate courtship displays, which often involve dance-like movements and vocalizations. Pelicans are found in a variety of habitats including wetlands, rivers, and coastal areas. Many pelican populations are considered to be at risk due to habitat loss, hunting, and other human activities. Conservation efforts have helped to increase the populations of some pelican species, but many species are still considered to be at risk.
