Little Shearwater
Puffinus assimilis

Map of the common names

Small shearwater (L 25 cm) with blue legs and black crown. The species breeds in rocky ground, caves, cliffs or stone walls. Unlike other shearwaters, Little Shearwater seems to be largely confined to the waters close to the breeding islands and visits the nesting sites outside the breeding period. The diet comprises mostly fish. The species is sendentary.

Reasons for the need for protection/inclusion in annex I
The endemic European race is P. assimilis baroli and has a total population of 3,500-4,000 pairs. In the Canaries as well as in some areas of Madeira and in the Azores, rats seem to be a major problem for the species. Little Shearwater could also be affected by deterioration of habitat (the upset of ground through the cliffs), by taking of nestlings and by coastal building projects (increase of artificial lighting).
