Ecology and Status
Yelkouan Shearwaters breed on islands and coastal cliffs in the eastern and central Mediterranean. Most winter in that sea, but small numbers enter the Atlantic in late summer. This species nests in burrows which are only visited at night to avoid predation by large gulls.
This is a gregarious species, which can be seen in large numbers from boats or headlands, especially in autumn. It is under some threat from the development of holiday resorts near its breeding sites, and also from animals such as cats and rats. The Yelkouan Shearwater feeds on fish and molluscs. It follows fishing ships when offal is being thrown.
The study of the Minorcan colony concluded that at least in these westernmost birds, genetic variation was extremely low, suggesting that the Yelkouan Shearwater may have suffered a marked population decline historically and thus, while not threatened judging from its absolute numbers, could be vulnerable to adverse effects of inbreeding.
It was formerly classified as a Species of Least Concern by the IUCN. But new research has shown it to be rarer than it was believed. Consequently, it was uplisted to Near Threatened status in 2008 and Vulnerable in 2012.

Famous quotes containing the words status and/or ecology:
“Knowing how beleaguered working mothers truly areknowing because I am one of themI am still amazed at how one need only say I work to be forgiven all expectation, to be assigned almost a handicapped status that no decent human being would burden further with demands. I work has become the universally accepted excuse, invoked as an all-purpose explanation for bowing out, not participating, letting others down, or otherwise behaving inexcusably.”
—Melinda M. Marshall (20th century)
“... the fundamental principles of ecology govern our lives wherever we live, and ... we must wake up to this fact or be lost.”
—Karin Sheldon (b. c. 1945)
