Pelicans are large aquatic birds that live near the oceans and large inland waterways. Types of Pelicans: There are eight types of Pelicans, For types build nests in trees (the Brown, the Spot-billed, the Pink-backed and the Peruvian pelicans) while the other four build nests on the ground (the American White, the Great White, the Australian and the Dalmatian pelicans). Geographic Range: Pelicans can be found along coastlines and waterways on every continent except Antarctica. Length: Adult Pelicans are from 4.1–6.0 feet (1.25–1.8 m) in length. Wings: Pelicans have large wings measuring from 6 to 10 feet (1.8 – 3 m) from wingtip to wingtip. This gives them great stability in flying and gliding as they search for food. Some pelicans migrate with the seasons. Weight: Adult Pelicans can weigh from 6 to 33 lbs ( 2.7 – 15 kg ). Food: Pelicans mostly eat fish. They may also eat crabs, shrimp, and other small sea or water life.
