This species breeds on Madeira, the Azores and the Berlengas Archipelago in Portugal and the Canary Islands in Spain. They nest on open ground or among rocks or less often in a burrow where one white egg is laid. The burrow is visited at night to minimise predation from large gulls. In late summer and autumn, most birds migrate into the Atlantic as far north as the south-western coasts of Great Britain and Ireland. They return to the Mediterranean in February. The biggest colony is located in Savage Islands, Madeira.
