About the Black-bellied Storm-Petrel

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

GBIF citizen-science records

It is estimated from how often the Black-bellied Storm-Petrel is recorded against all the birds logged in Antarctic Peninsula & South Shetland Islands (274 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.
