Balearic Shearwater

• GeneralThe most threatened seabird in Europe; it breeds only in the Balearics.
• conservaciónIt is one of the most threatened seabirds in Europe, breeding almost entirely in the Balearic Islands, with a small world population.
• It is a strict Spanish endemic: every colony in the world is in the Balearics, and Spain is therefore directly responsible for the future of the species.
• Its wintering range has been shifting northwards over recent decades, following the movement of small pelagic fish populations as the Atlantic warms.
• Population models give it a mean life expectancy of a few decades if current mortality rates from longlining and introduced predators continue.
