Site description Pearl Rocks lie several km offshore from the western coast of Tower Island, ~25 km from the Davis Coast of the Antarctic Peninsula. Pearl Rocks are uncharted, so the IBA has been defined as an elliptical area centered on the approximate position of the northernmost of the three highest islets in the Pearl Rocks group.
Information on the environment at Pearl Rocks is not available. The nearest permanent scientific stations are Gabriel de Castilla (Spain) and Decepción (Argentina), located ~80 km to the northwest at Port Foster, Deception Island. These summer-only stations have a combined capacity of 90 people.
Key Biodiversity Around 170 breeding pairs of Imperial Shag were recorded in 1987 (Poncet & Poncet, unpublished data). No other birds are known to breed at this site.
Non-bird biodiversity: Several small colonies of Chinstrap Penguins (Pygoscelis Antarctica) are located on the coast of nearby Tower Island, where Southern Fulmar (Fulmaris glacialoides) and Cape Petrel (Daption capense) have also been recorded as breeding.
