Reasons for the need for protection/inclusion in annex I
The difficulties involved in carryng out censuses mean that population trends are very poorly known. Nevertheless, it is thought that the breeding population is around 100,000 pairs. The species is particularly susceptible to introduced predators (rats or cats) on breeding sites. Disturbance by tourists, military bombing and sea pollution are also listed as negative factors.
