Pelicans are a variety of enormous water feathered creatures that make up the family Pelecanidae. They are described by a long mouth and a huge throat pocket utilized for getting prey and emptying water of the gathered up substance before gulping. They have overwhelmingly pale plumage, the special cases being the earthy coloured and Peruvian pelicans.

The bills, pockets, and uncovered facial skin of all species become splendidly hued before the rearing season. The eight living pelican species have a sketchy worldwide conveyance, extending latitudinally from the tropics to the calm zone, however, they are missing from inside South America and from polar areas and the untamed sea. 

Since quite a while ago idea to be identified with frigatebirds, cormorants, tropicbirds, and gannets and boobies, pelicans rather are currently known to be most firmly identified with the shoebill and hamerkop and are submitted in the request Pelecaniformes. Ibises, spoonbills, herons, and bitterns have been grouped in a similar request.

 Fossil proof of pelicans goes back at any rate 30 million years to the remaining parts of a bill fundamentally the same as that of present-day species recuperated from Oligocene layers in France. They are thought to have developed in the Old World and spread into the Americas; this is reflected in the connections inside the sort as the eight species separate into Old World and New World heredities. 

Pelicans regular inland and seaside waters, where they feed chiefly on fish, getting them at or close to the water surface. They are gregarious fowls, going in herds, chasing agreeably, and reproducing provincially. Four white-plumaged species will in a general home on the ground, and four earthy coloured or dim plumaged species home primarily in trees.

 The connection between pelicans and individuals has regularly been petulant. The fowls have been aggrieved in light of their apparent rivalry with business and recreational fishing. Their populaces have fallen through territory pulverization, aggravation, and natural contamination, and three species are of protection concern. They additionally have a long history of social importance in folklore, and Christian and heraldic iconography.
