Fregetta tropica
In 3 days <5%
The black-bellied storm petrel (Fregetta tropica) is a species of seabird in the family Oceanitidae. It is found in Antarctica, Argentina, Australia, Bouvet Island, Brazil, Chile, Falkland Islands, French Polynesia, French Southern Territories, Madagascar, Mozambique, New Zealand, Oman, Peru, Saint Helena, São Tomé and Príncipe, Solomon Islands, South Africa, South Georgia and the South Sandwich Islands, Uruguay, and Vanuatu.
They are usually black with a white band over the rump and white under the wings and on the flanks. A broad black stripe runs down the center of the belly, but may be broken or absent altogether. They have long legs, so the feet can be seen beyond the tail in flight. The legs and feet are black.
They are silent mostly at sea. Noises can be heard from the breeding colonies; birds on the ground give a drawn-out shrill whistle. Black-bellied storm-petrel [Fregetta tropica] – photos, Christopher Taylor Nature Photography

Rare
Under 5% of wildlife watchers report a Black-bellied Storm-Petrel sighting in Falkland Islands on a given day, based on 11 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 74th most-seen of the 79 birds we can rate there. Over three days the chance rises to under 5%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Black-bellied Storm-Petrel in Falkland Islands on a given day, so our monthly data shows no clear season.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Black-bellied Storm-Petrel sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
3rd of 3
Of the 3 parks where we can rate Black-bellied Storm-Petrel sightings, Falkland Islands ranks 3rd at under 5%. The best odds are in Antarctic Peninsula & South Shetland Islands (Antarctica, about 20%) and South Georgia and the South Sandwich Islands (South Georgia and the South Sandwich Islands, about 20%).
GBIF citizen-science records
It is estimated from how often the Black-bellied Storm-Petrel is recorded against all the birds logged in Falkland Islands (11 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.
