Surely one of the stars of Mor Braz, since we can find several hundred (even thousands) of individuals! This shearwater breeds only on the Balearic archipelago. Its population is estimated at about 20,000 individuals. The Morbihan waters play an important role in the migration and dispersal of this species considered to be in critical danger of extinction.
➢ To spot it: with binoculars, often low-flying
➢ To identify it: silhouette and shearwater (long wings kept straight, alternating series of hovers and wing beats); differs from the Manx Shearwater by its more "dirty", faded and low contrasting appearance (brown and dirty white).
