There are three oceanic bird species called gannet. They are found in the North Atlantic, where they are the largest seabirds, and in temperate seas around Africa, Australia, and New Zealand. The adults are mainly white with black-tipped wing feathers and a large, yellowish or buff-colored head, with black around the eyes. They have a tapered beak and pointed tail. They dive with half-closed wings to catch fish and squid. They waddle on land, but are expert fliers, spending most of their lives over water. They nest in dense colonies on cliffs. The largest species is the 40-in (100-cm) northern gannet.
