The Fea's Petrel ( Pterodroma feae ) is a bird art from the order of the tube lugs (Procellariiformes). Knowledge about this sea bird is quite limited.
Mark
The Cape Verde petrel has almost completely dark under wing coverts, a (brown-) gray upper side with a dark W pattern, a monochrome light gray upper tail, and gray-washed breasts. The bird reaches a length of 33 to 36 cm and a wingspan of 86 to 94 cm. The utterances of this tubular nose can only be heard at night in the colonies : plaintive sounds that are sometimes ended with an almost hacking tone.
Problems in identification and possible confusion
When discovering this type, disruptive factors must not be underestimated: The W pattern is often not recognizable due to too great a distance or unfavorable lighting conditions. In addition, there are some species with which the Cape Verde petrel can be confused if the observation time is only relatively short or if there is no precise knowledge of the species: If you look inaccurately, the bird reminds you of a small yellow-billed shearwater ( Calonectris diomedea ), which is a pure one has white underside. However, it is practically indistinguishable from the Madeira petrel ( Pterodroma madeira ), whose beak looks a bit smaller. In addition, the head of the sister species should appear a little lighter, which is hardly noticeable when observing.
distribution
The Cape Verde petrel breeds, as the name suggests, on Cape Verde , but also on Bugio in the Desertas archipelago . The Cape Verde petrels that breed on Bugio are sometimes separated as the endemic species Pterodroma deserta . The clan is endangered according to the IUCN Red List.
The breeding colonies of the Cape Verde petrel are small. It is usually incubated in late summer / autumn.
Occurrence in Europe
The Cape Verde petrel is a wanderer in Europe who occasionally appears in the west of the continent .
