Description
Long thought to be related to frigatebirds, cormorants, tropicbirds, gannets and boobies, pelicans are now known instead to be most closely related to the Shoebill and Hammerkop, and are placed in the order Pelecaniformes. Ibises, spoonbills and herons are more distant relatives, and have been classified in the same order. Pelicans frequent inland and coastal waters where they feed principally on fish, catching them at or near the water surface. Gregarious birds, they often hunt cooperatively and breed colonially. Four white-plumaged species tend to nest on the ground, and four brown or grey-plumaged species nest mainly in trees.
�.
Pelicans are very large birds with very long bills characterized by a down curved hook at the end of the upper mandible, and the attachment of a huge gular pouch to the lower. The slender rami of the lower bill and the flexible tongue muscles form the pouch into a basket for catching fish and, sometimes, rainwater though in order not to hinder the swallowing of large fish, the tongue itself is tiny. They have a long neck and short stout legs with large, fully webbed feet. Although they are among the heaviest of flying birds, they are relatively light for their apparent bulk because of air pockets in the skeleton and beneath the skin enabling them to float high in the water. The tail is short and square. The wings are long and broad, suitably shaped for soaring and gliding flight, and have the unusually large number of 30 to 35 secondary flight feathers.

The chains and netting he's on and the blurred background all excellant points of intrest

Wonderful portrait of a pelican - love the netting captured with it, gives so much texture. v/f
