and sheathbills. Breeding success increases as the parents mature, improving from 48% at age 6–8 to 87% at age 18–20. Feeding Southern fulmars frequently gather in flocks, often with other species of seabird such as Cape petrels, when there is a concentration of food like a school of krill or around whaling ships and trawlers. Krill and other crustaceans are the most important component of the diet but the species also feeds on small fish such as the Antarctic silverfish and squid such as Psychroteuthis, Gonatus and Galiteuthis. Food is usually picked from the surface of the water but the bird will occasionally dive.
