Great White Pelican Scientific Name: Pelecanus onocrotalus Range: Eastern Europe to Western Mongolia; Sub-Saharan Africa Habitat: Freshwater lakes, deltas, marshes or swamps Natural Diet: Fish and some crustaceans Zoo Diet: Fish Physical  Characteristics: Great white pelicans are white with black wing feathers, a large bill tipped with red, a yellow pouch under the bill, and yellow feet.  Males are about 70 inches long and weigh 20-33 pounds; females are about 60 inches long and weigh 11-20 pounds. Behavior: Great white pelicans live, breed, migrate, feed, and fly in formation as part of a large colony.   To feed, the pelican scoops up fish in the skin pouch below the bill; then it tilts up its bill and swallows the fish whole.  They are excellent swimmers.  To defend its territory, a male will threaten intruders by clapping its bill and bowing.  They will also attack with their bill. Reproduction: Pelicans usually nest in colonies.  The nest, a pile of sticks or little more than bare rock, is on the ground.  The eggs have an incubation period of 29-36 days.  The young are able to fly in 65-75 days.
