Pelicans are large water birds that are found throughout the world in both freshwater and saltwater habitats. Here are some of their key characteristics:

  1. Size: Pelicans are among the largest of all bird species. The largest species, the Dalmatian Pelican, can weigh up to 15 kg (33 lb) and have a wingspan of up to 3.5 m (11 ft).

  2. Beak: Pelicans have a unique, elongated bill that is typically larger than their head. The bill is designed to scoop up water and fish, and it can hold up to 3 gallons of water.

  3. Pouch: In addition to their bill, pelicans also have a stretchy throat pouch that they use to store and carry fish. The pouch can expand to hold large amounts of food, making it easier for pelicans to swallow their prey.

  4. Feathers: Pelicans have a waterproof layer of feathers that helps keep them dry and buoyant while swimming. They also have a layer of downy feathers that provides insulation and helps regulate their body temperature.

  5. Flight: Despite their large size, pelicans are excellent fliers. They have strong wings that allow them to soar for long periods of time, and they can reach speeds of up to 56 km/h (35 mph).

  6. Diet: Pelicans are primarily fish-eaters, but they also consume crustaceans and other aquatic creatures. They use their bill and pouch to scoop up prey from the water, and they are known for their spectacular aerial dives to catch fish.

  7. Social behavior: Pelicans are generally social birds and often hunt and nest in groups. They are also known for their unique courtship rituals, which involve elaborate displays of plumage and vocalizations.
