The southern fulmar is a seabird of the Southern Hemisphere. Along with the northern fulmar, F. glacialis, it belongs to the fulmar genus Fulmarus in the family Procellariidae, the true petrels. It is also known as the Antarctic fulmar or silver-grey fulmar.
Region
Southern Ocean and Subantarctic
Typical Environment
Breeds on coastal cliffs and rocky headlands around Antarctica and subantarctic islands, then disperses widely across the Southern Ocean outside the breeding season. Most abundant along the pack-ice edge, productive shelf breaks, and upwelling zones. Regularly ranges north into subantarctic waters off South America, southern Africa, Australia, and New Zealand. Occurs almost entirely offshore, coming to land only to breed.
Altitude Range
Sea level to 600 m
Climate Zone
Polar
Ease of Keeping
Beginner friendly: 1/5
A southern-hemisphere tubenose, the southern fulmar produces an energy-rich stomach oil used to feed chicks and as a defensive spray against predators. It often follows fishing vessels and whales to scavenge food and can range thousands of kilometers over the Southern Ocean. Long-lived and highly philopatric, it returns to the same cliff colonies year after year.
In flight
Egg of Fulmarus glacialoides
Temperament
social and active at sea, territorial at nest sites
Flight Pattern
dynamic soaring and gliding with occasional stiff wingbeats
Social Behavior
Breeds colonially on cliff ledges, laying a single egg in a shallow scrape. Both sexes share incubation and chick-rearing duties, often maintaining long-term pair bonds. Outside the breeding season it forms loose flocks and congregates where food is abundant, including near fishing vessels.
Migratory Pattern
Seasonal migrant
Song Description
Mostly silent at sea. At colonies, gives harsh cackles, croaks, and chuckling calls during courtship, territorial disputes, and pair recognition.
