Europe's smallest seabird (L 15 cm). At distance looks all-black apart from snow-white rump. Also has a square-ended tail. Storm Petrels require breeding islands free of mammalian predators. Nests are placed either in burrows, in rocks crevices or under boulders. Outside the breeding period, birds are found widely over the continental shelf, including the edge. They feed on crustaceans and small fishs. Migrant.
Reasons for the need for protection/inclusion in annex I
Although the popualtions are probably stable, those on the Mediterranean have declined in recent years. The major threat is the accidental introduction of mammalian predators to breeding sites, the Storm Petrel beeing highly susceptible to such predation as the majority of is concentrated in relatively few sites. This is particularly the case in the Mediterranean where breeding populations are small and confined to just a few islands.
