Pelicans belong to the Pelecanidae family and are known for their long beaks and big throat pouches. These features help them catch prey and drain water from their catch. There are eight living pelican species found all over the world, from the tropics to the temperate zone.
However, they are not found in the interior of Amazonian South America, the polar regions, or the open ocean. But, they can travel hundreds of miles inland in North America. They follow large waterways like the Mississippi River.
Introduction to Pelicans
Pelicans belong to the Pelecanus genus and the Pelecanidae family. They are known for their long beaks and large throat pouches. These features help them catch prey and drain water before swallowing. Let’s dive into their unique traits and behaviors.
Physical Characteristics and Behavior
Pelicans have mostly pale feathers, except for the brown and Peruvian pelicans. Before breeding, their bills, pouches, and skin turn brightly colored. They are social birds, living in large groups, hunting together, and breeding in big colonies.
The four white pelicans nest on the ground, while the four brown or grey ones nest in trees. They have a huge wingspan, up to 3 meters (10 feet), and can weigh up to 13 kg (30 pounds).
“Pelicans can have a wingspan of up to 3 meters (10 feet) and weigh up to 13 kg (30 pounds).”
Pelicans are not just beautiful; they have interesting behaviors too. They are great at soaring and dipping their beaks into the water to catch fish. This shows their amazing hunting skills.
As we learn more about pelicans, we’ll look into different types and their unique traits. Stay tuned for more interesting facts about these amazing birds!
Types of Pelicans
The Pelecanidae family has eight distinct pelican species, each with its own special traits. These birds can be split into two main groups. Four species live on the ground and have white feathers as adults. The other four live in trees or on sea rocks and have grey or brown feathers.
Let’s look at the different types of pelicans found worldwide:
- American White Pelican (Pelecanus erythrorhynchos)
- Brown Pelican (Pelecanus occidentalis)
- Peruvian Pelican (Pelecanus thagus)
- Great White Pelican (Pelecanus onocrotalus)
- Australian Pelican (Pelecanus conspicillatus)
- Pink-backed Pelican (Pelecanus rufescens)
- Dalmatian Pelican (Pelecanus crispus)
- Spot-billed Pelican (Pelecanus philippensis)
These pelicans live in warm places all over the world, except Antarctica. They are known for their big pouches. They use these to catch fish and to cool down by fanning the air.
