The Mascarene Typhoon (Latin Pseudobulweria aterrima) is a rare species of birds of the petrel family that nests on Reunion Island.
Mascarene typhoon reaches a length of 36 cm. The plumage is predominantly dark chocolate in color. The chin and upper throat are lighter. The underside of the wings is more silvery. The beak and legs are black. A reddish spot can be seen in the middle of the swimming membranes. The call-up call consists of whistling sounds.
Little is known about the lifestyle of the Mascarene typhoon. All nesting holes were found in vegetation on the cliffs. The bird nests in the southern summer. The nesting period begins in December, and from February to March, the chicks become independent.
The Mascarene Typhoon was known for a long time from only four museum specimens of the 19th century, until, since 1964, information about the observation of this species in the waters south of Réunion began to arrive. In 1970, 1973 and January 1995, 3 dead birds were found. Then 5 nesting sites with 9-10 nesting pairs were found on Reunion. A total of 26 birds were sighted in the open ocean between 1978 and 1995, but there was no record of birds more than 500 km from Réunion.As with the Typhoon Baro (Pterodroma baraui), which also lives on Reunion, the main threat to birds comes from rats and feral cats. Another threat, especially for young, inexperienced birds, is light pollution. The light from street lamps and lighting installations on sports grounds causes young birds to be seriously injured and killed in collisions. The actual size of the population is unknown. BirdLife International estimates a global population of between 90 and 800 individuals and classifies the species as endangered.
