Great White Pelican
Great White Pelicans are large birds with mass of 10 kg (22 lbs), 160 cm (63 in) long and with a 280 cm (110 inch) wingspan. It differs from the Dalmatian Pelican, the only larger species of pelican, by its pure white, rather than greyish-white, plumage, a bare pink facial patch around the eye and pinkish legs. Males are larger than females, and have a long beak that grows in a downwards arc, as opposed to the shorter, straighter beak of the female. Immature birds are grey and have dark flight feathers. In flight, it is an elegant soaring bird, with the head held close to and aligned with the body by a downward bend in the neck. In breeding condition the male has pinkish skin on is face and the female has orangery skin
Well scattered groups occur from the eastern Mediterranean through to Vietnam and south to South Africa. Sedentary populations are found year-round in Africa, south of the Sahara Desert although these are patchy, occurring mainly in coastal, estuarine areas and around very large inland water bodies.[3] Migratory populations are found from Eastern Europe to Kazakstan during the breeding season and from northeast Africa through Iraq to north India in the winter. More than 50% of Great White Pelicans breed in the Danube Delta in Romania.
The diet of the Great White Pelican consists mainly of fish. Each pelican needs about 1.4 kg of fish every day. This corresponds to around 28 million kilograms of fish every year consumed at the largest colony of Great White Pelicans, on Tanzania’s Lake Rukwa, with almost 75000 birds. Pelicans are not restricted to fish, however, and are often opportunistic foragers. In some situations they eat chicks of other birds, such as the well documented case off the southwest coast of South Africa.[4] Here breeding Pelicans from the Dassen Island colony predate chicks up to 2 kg from the Cape Gannet colony on Malgas Island.[5] Great White Pelicans also eat crustaceans, tadpoles and even turtles. They readily accept handouts from humans, and a number of unusual items have been recorded in their diet. During periods of starvation, pelicans also eat seagulls and ducklings. The gulls are held under water and drowned before being eaten headfirst. Pelicans will also rob other birds of their prey. [edit] Relationships with humans In flight Today, because of overfishing in certain areas, White Pelicans are forced to fly long distances to find food. Great white pelicans are exploited for many reasons. Their pouch is used to make tobacco bags, Their skin is turned into leather, the guano is used as fertiliser, and the fat of young pelicans is converted into oils for traditional medicine in China and India. Human disturbance, loss of foraging habitat and breeding sites, and pollution are all contributing to the decline of the Great White Pelican
