Behavior

Commonly flies at high speed in very high (10/40 metres) “Vs” above the sea, rarely beating its wings. There are no differences between males and females.

Habitat

This species is endemic to Macaronesia and nests in Madeira archipelago (on Bugio – one of the Desertas islands) and on the Cape Verde islands of São Nicolau, Santiago, Fogo and Santo Antão.

Distinction from similar species

It easily confused with Zino's Petrels due to its similar characteristics though Fea's / Desertas Petrels are slightly bigger with a much heavier bill.

Other Bird Facts

Seasonality in Madeira: These seabirds are observed flying around Madeira between mid May and mid November.
Breeding: On the Southern plateau of Bugio this seabird normally nests in unused rabbit burrows or ones that it excavates itself where the ground is soft with sufficient soil. It also nests in holes in rocks or in zones with loose stones, the latter habitat being more common in Cape Verde.
Fea's Petrels arrive to Madeira waters around June, lay a single egg in summer (July/August) and the young birds leave the nests in December. In Cape Verde this species appears to lay its eggs in December/January.
Diet: It feeds on squid, small fish and surface crustaceans

Status

Madeira local status by Romano et al, 2010: Rare breeding bird
Madeira local status by Zino et al, 1995: Very rare breeding bird
Conservation status by the IUCN Red List Categories, 2013: Near Threatened ver 3.1

Curiosities
There are some reasons to think that the Cape Verde population of Fea's Petrel may be a separate species and some taxonomic authorities (Avibase, IOU - International Ornithologists’ Union - former IOC) already consider them as 2 different species - Pterodroma deserta and Pterodroma feae - but the data supporting this line of thought is still inconclusive. The described ID differences are small and are expected on island colonies, also the different breeding seasons are understandable when colonies are geographically distinctive.
