Pelicans often travel in large flocks, visiting the mouths of rivers or favorite retreats on the sea-coast. When they have made choice of a suitable fishing place, they arrange themselves in a wide circle, and begin to beat the water with extended wing, so as to drive the Fish before them, gradually diminishing the circle as they approach the shore or some inlet on the coast. In this manner they get all the Fish together into a small space, when the common feast begins. After gorging themselves, they retire to the shore, where the process of digestion follows. Some rest with the neck over the back; others busily dress and smoothe their plumage, waiting patiently until returning appetite invites them to fresh exertions. When thus resting, occasionally one of these Birds empties his well-lined pouch, and spreads in front of him all the Fish that it contains, in order to feed upon them at leisure. In spite of its great size, the Pelican flies easily and to considerable distances. It does not dive but will occasionally dash down on Fish from a considerable height, and with such force that it becomes submerged; but its buoyancy instantly brings it again to the surface. It perches on trees, but seems to prefer rocks. The nest is generally formed of coarse, reedy grass, lined with softer material and placed in the clefts of dry rocks near the water. Occasionally they will lay in an indentation in the ground which they have previously roughly lined with blades of grass. The Pelican is more common in tropical regions than in temperate climates. They are very numerous in Africa, Siam, Madagascar, the Sunda Isles, the Philippines; and in the Western Hemisphere they abound from the Antilles to the northern temperate part of the North American continent. They haunt the neighborhood of rivers and lakes and the sea-coast. The best known species are—first, the Crested Pelican; second, the White Pelican; third, the Brown Pelican; fourth, the Spectacled Pelican. THE CRESTED PELICAN. The Crested Pelican in common with the White Pelican, inhabits the southeast of Europe and Africa, and is also found in Hungary, Dalmatia, Greece, the Crimea, and the Ionian Islands, as well as in Algeria, and, according to some authors, it is frequently met with in China. It has white plumage, with the exception that the ends of the feathers of the back and wings are black. The feathers of the head and upper part of the neck are twisted up so as to form a large tuft or crest, hence the name it bears. Its European home is principally the marshes round the Black Sea. Of their modes of life travelers in those regions give very interesting descriptions.
