Storm petrels fact sheet

Oceanodrama spp. | Storm petrels

In the Azores it is possible to see five species of storm petrel (Wilson's Leach’s, Madeiran, Monteiro’s and White-faced) that are difficult to disitnguish at sea.  They are the smallest seabirds in Azores and not sighted frequently. In the Azores, storm petrels are classified as "rare vagrants" and the Monteiro's storm petrel is classified as being "rare breeding". The Monteiro’s storm petrel (Oceanodrama monteiroi) is endemic to the Azores and nests (from May to early December) only on the islet of Praia, in Graciosa. The population has been reduced to just 250-300 breeding pairs. They are able to reproduce from two years on and the females produce just one egg each time. The egg is laid between late April until early July. The parents take care of the single chick for two months, with both parents participating in incubation and vigilance. The newborns leave the nest between mid-August and early October. During the day they catch small fish and squid. At night, they eat mesopelagic organisms that make  nocturnal migrations to the surface.
