Mascarene Black Petrels

The Mascarene Black Petrel (Pseudobulweria aterrima) is only known from four specimens found in the nineteenth century on the island of Réunion. Two birds were found dead in the 1970s, and there have been rare observations of birds in the waters south of Réunion since 1964.

Status
