Fea's Petrel (Pterodroma feae) is a small seabird in the gadfly petrel genus, Pterodroma. It was previously considered to be a subspecies of the Soft-plumaged Petrel, P. mollis, but they are actually not closely related at all. However, P. feae is very closely related to Zino's Petrel and Desertas Petrel, two other species recently split from P. mollis.


The gadfly petrels in the genus Pterodroma are seabirds of temperate and tropical oceans. Many are little-known and poorly studied, and their often similar appearance has meant that the taxonomy of the group has been rather fluid.The forms breeding in Macaronesia on Madeira, Bugio in the Desertas Islands, and in the Cape Verde archipelago were long considered to be subspecies of the southern hemisphere Soft-plumaged Petrel P. mollis, but differences in size, vocalisations, breeding behaviour and mitochondrial DNA analysis showed that the northern birds are not closely related to P. mollis, and that the Bermuda Petrel or Cahow may be the closest relative of the Macaronesian birds.Sangster recommended establishing Zino's Petrel on Madeira and Fea's Petrel on the Desertas and Cape Verde as full species,and the species split was accepted by the Association of European Rarities Committees (AERC) in 2003.More recently, some authorities have further split Fea's Petrel, separating the Desertas Islands breeding birds from those in the Cape Verde archipelago.

Sangster estimated that the two Macaronesian species they diverged at the end of the Early Pleistocene, 850,000 years ago, although the methodology used to establish this time scale has subsequently been questioned.An analysis of feather lice from Fea's Petrel's Pterodroma feae deserti from Bugio Island and Zino's Petrels from the Madeiran mainland showed that there were marked differences between the two seabirds in terms of the parasites they carried, suggesting that they have long been isolated, since lice can normally only be transferred through physical contact in the nest. The species on Zino's Petrel are most similar to those of the Bermuda Petrel, whereas Fea's Petrel's lice are like those of Caribbean and Pacific Pterodromas. This suggests that despite the close physical proximity of the two species of gadfly petrel found in the Madeiran archipelago, they may have arisen from separate colonisations of mainland Madeira and, later, the Desertas Islands.

This bird is named after the Italian zoologist Leonardo Fea.


This long-winged petrel is 33–36 cm in length with an 86–94 cm wingspan. It has a grey back and wings, with a dark "W" marking across the wings. The undersides of the wings are dark and the belly is white. It has a fast impetuous flight. It picks planktonic food items from the ocean surface. This species is very similar to the Zino's Petrel, but is larger and has a thicker black bill.

As all three of species in the Pterodroma feae/madeira/desertae complex were once believed to be subspecies of a single species: Pterodroma mollis. Well-understood is the extreme difficulty in telling them apart.

Distribution and habitat

It breeds in the north Atlantic in the Cape Verde Islands and Madeira Islands (Bugio Island).

Pterodroma feae/madeira records in the US

It is a rare visitor to waters off the eastern US, though known only from sight records and photographs. The American Ornithologists' Union has not accepted these records, and the American Birding Association has accepted them only as "Fea's/Zino's Petrel".

Pterodroma feae/madeira records in Europe

It is also an extremely rare vagrant to western Europe, principally Great Britain and Ireland, though most records there are also acceptable only as "Fea's/ Zino's", with the exception of three at-sea records in British waters.


This seabird is strictly nocturnal at the breeding sites to avoid predation by gulls. Like most petrels, its walking ability is limited to a short shuffle to the burrow. This endangered species nests in colonies in burrows in spring and autumn. It lays a single white egg.
