This species is marine and highly pelagic, usually being found far from land except during the breeding season. Nests can be burrows, crevices, cracks or caves, under debris or vegetation cover. Its diet comprises mainly of fish and squid, with minor proportions of crustaceans and sea-striders, feeding largely at night by surface-seizing (Carboneras et al. 2014).

Although the generation length for both EU and Europe regional assessments were calculated using the same methodology, new information arriving after the EU assessments were undertaken gave rise to an update in the generation lengths. This new information was then used for the Europe level assessments giving rise to a difference between the generation lengths used for the EU and Europe regions.

In Europe, this species breeds almost entirely in Madeira (Portugal), with small populations also present in the Canary Islands (Spain) and the Azores (Portugal).

Conservation Actions Underway
It is listed under Appendix II of the Bern Convention, and under Annex I of the EU Birds Directive. It is currently listed as occurring in 26 marine Important Bird Areas. In the EU it is listed within 23 Special Protection Areas.

Conservation Actions Proposed
Ongoing management and eradication of invasive predators at breeding colonies; enforcement and regulation of human exploitation; mitigation and reduction of light pollution from shipping and human settlements; bycatch monitoring on board vessels and reduction and mitigation on fishing vessels where appropriate.
