European Storm-Petrel

Hydrobates pelagicus

The European storm petrel, also known as British storm petrel, or just storm petrel, is a species of seabird in the northern storm petrel family, Hydrobatidae. The small, square-tailed bird is entirely black except for a broad, white rump and a white band on the under wings, and it has a fluttering, bat-like flight. The large majority of the population breeds on islands off the northern coasts of Europe, with the greatest numbers in the Faroe Islands, United Kingdom, Ireland, and Iceland. The Mediterranean population is a separate subspecies whose strongholds are Filfla Island (Malta), Sicily, and the Balearic Islands. This subspecies is indiscernible at sea from its Atlantic relatives. Source
