Fulmar, a gull-like ocean bird distinguished by its stiff-winged, gliding flight. It has a stubby yellow bill with tubelike nostrils. Fulmars are 17 to 20 inches (43 to 51 cm) long. Most are white with pale gray wings, tails, and backs. The fulmar feeds on fish, squid, crustaceans, and ships' refuse. It comes to land only to breed. The female lays one white egg in a shallow depression on a rocky cliff. The fulmar's range extends from the Arctic Ocean south to Newfoundland and the British Isles. Some fulmars winter off the coast of New Jersey.

The fulmar is Fulmarus glacialis of the shearwater family, Procellariidae.
