Manx Shearwater (Balearic subspecies)
Puffinus puffinus mauretanicus

Map of the common names

Small seabird (L 35 cm), but with a big wingspan (90 cm). Black bill with grey on the base and grey legs with pink feets. Nests are amongst rock crevices, recesses or burrows in cliffs and small island. The birds feed on small fishs, cephalopods and crustaceans. Migrant. There are several sub-species, previously considered races of Puffinus puffinus. Today, this denomination is reserved for the Atlantic population, whereas the Mediterranean population is called P. yelkouan. The sub-species mauretanicus breeds in the Baleairc Islands and the sub-species yelkouan breeds in the rest of the Mediterranean.

Reasons for the need for protection/inclusion in annex I
The population is estimated around 3.300 breeding pairs. The main threat to the species is the limited population size and distribution. The taking of eggs and chicks and the hunting of adults by man have presumably long been a serious threat, and remain so at some places (Formentera). It is also threatened by predation from rats and cats.
