booby (redirected from boobies)

booby, common name for some members of the family Sulidae, large, streamlined sea birds. Tropical and subtropical members of the family are called boobies; those of northern waters are called gannets. These birds have heavy bodies; long, pointed wings; long, wedge-shaped tails; and short, stout legs. They fish by diving on their prey from great heights and pursuing it underwater; air sacs under their skin cushion the impact with the water and provide buoyancy, as with pelicans. The masked, red-footed (Sula sula), and brown (S. leucogaster) boobies are found the world over; the Peruvian and blue-footed (S. nebouxii) boobies, on the west coasts of the Americas; and the Abbott's booby, in the Indian Ocean. The common gannet of the North Atlantic, Morus bassanus, breeds in the British Isles, in the Gaspé region of Canada, and on Bird Island in the Gulf of St. Lawrence. A Pacific gannet is one of the chief guano producers of the offshore islands of Peru. Gannets build crude nests of debris on narrow cliff ledges. The female lays a single egg, which she and the male incubate by covering it with their feet. Gannets have strong migration tendencies, while the boobies do not. The name booby is descriptive not only of the rather stupid facial expression of these birds, but also of their unwary, gullible behavior when hunted by man—a factor that accounts for their diminishing numbers. Boobies and gannets are classified in the phylum Chordata, subphylum Vertebrata, class Aves, order Pelecaniformes, family Sulidae.

booby

Any of six or seven species of large tropical seabirds (family Sulidae), named for their presumed lack of intelligence. Two common species are wide-ranging in the Atlantic, Pacific, and Indian oceans; another is found in the Pacific from southern California to northern Peru and on the Galápagos Islands. The booby has a long bill, cigar-shaped body, and long, narrow, angular wings. It flies high above the ocean looking for schools of fish and squid, which it snatches in a vertical dive. Boobies vary in length from 25 to 35 in. (65–85 cm). They nest in colonies but are territorial.
