Then it dives into the water to catch the fish. Pelicans are almost always seen in flocks. While flying, American white pelicans may gather in flocks of up to 1,000 birds. These birds may soar upward in tight circles on a rising current of hot air called a thermal. They often soar so high that they disappear from sight.
Some pelicans nest in trees.
They build their nests out of twigs and other plant materials. Other pelicans nest in small hollows on the ground, usually on islands. Female pelicans lay two or three chalky-white eggs, which hatch in about a month. Pelicans are born without feathers. They cannot fly until they are about 10 to 12 weeks old.
