; class Aves, order Pelecaniformes)

A family that comprises the one genus Sula (although three species are sometimes placed in a separate genus, Morus) of large sea-birds, many of which are white with black flight feathers, others brown with varying amounts of white. They have long, stout bills, lacking nostrils, fairly long necks, long, pointed wings, and long, wedge-shaped tails. Their legs are short with large, totipalmate feet which are often brightly coloured. They inhabit islands and cliffs, feed on fish caught by diving from the air, and nest colonially on ledges, on the ground, or in trees. There are nine species, some migratory, found world-wide.
