The southern fulmar (Fulmarus glacialoides) 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.
It is largely pale grey above and white below with a distinctive white patch on the wing. It breeds on the coast of Antarctica and on surrounding islands, moving north in winter. It nests in colonies on cliffs, laying a single egg on a ledge or crevice. Its diet includes krill, fish and squid picked from the water's surface.
The southern fulmar formally described and illustrated in 1840 by the Scottish zoologist Andrew Smith in his major work Illustrations of the Zoology of South Africa. He placed it with all the other petrels in the genus Procellaria and coined the binomial name Procellaria glacialoides. The southern fulmar is now placed with the northern fulmar in the genus Fulmarus that was introduced in 1826 by the English naturalist James Stephens. The genus name comes from the Old Norse Fúlmár meaning "foul-mew" or "foul-gull" because of the birds' habit of ejecting a foul-smelling oil...

With luck
About 10% of wildlife watchers report a Southern Fulmar sighting in Falkland Islands on a given day, based on 135 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 47th most-seen of the 79 birds we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
May
In that month about 40% of wildlife watchers report a Southern Fulmar in Falkland Islands on a given day, against under 5% in January–March and July, the lowest months.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Southern Fulmar sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
2nd of 5
Of the 5 parks where we can rate Southern Fulmar sightings, Falkland Islands ranks 2nd at about 10%. The best odds are in Antarctic Peninsula & South Shetland Islands (Antarctica, about 70%).
Same family: Procellariidae
The closest relatives of the Southern Fulmar that you can see in Falkland Islands (family Procellariidae, Shearwaters and Petrels) are Southern Giant Petrel (about 70%), Sooty Shearwater (about 20%) and White-chinned Petrel (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Southern Fulmar is recorded against all the birds logged in Falkland Islands (135 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
