Fea's Petrel: where and when to see them

Fea's petrel is a Cape Verde breeding gadfly petrel adapted to wide-ranging oceanic life. Grey upperparts and pale underparts conceal a powerful flyer capable of sweeping arcs above the sea. Its nesting distribution is restricted, even though individuals travel far beyond the archipelago. Modern treatments separate it from the closely similar Desertas petrel, making older records and names potentially confusing. Most visitors are more likely to obtain a distant offshore glimpse than a clear shore-based identification.

Fea's petrels use wind to sustain long gliding flights, alternating banking arcs with periods of flapping. They range widely while feeding and return to nesting areas mainly at night. Pairs occupy concealed burrows or rock cavities, where a single egg is laid. Adults alternate incubation and feeding duties over a prolonged breeding cycle. Quiet colony behaviour and difficult terrain make nesting birds hard to observe, and introduced predators pose particular risks to eggs and chicks. Courtship displays often involve aerial pursuits and vocalizations at night near breeding sites. Adults are highly vulnerable to introduced predators such as cats and rats, which can decimate entire colonies. The single chick remains in the burrow for an extended period, relying on parental feeding trips before fledging.

• Its name commemorates the Italian naturalist Leonardo Fea.
• Under current species limits, its breeding range is confined to Cape Verde.
• It belongs to the gadfly petrels, named for their restless aerial style.
• Desertas petrel was formerly treated within the same species.

Late autumn through spring broadly overlaps breeding attendance in Cape Verde, although timing varies between islands and pairs. Distant deck observation remains possible outside that period. Wind, sea state and identification conditions matter, and breeding attendance does not make colonies appropriate visitor destinations. Peak breeding activity, including egg laying and chick rearing, typically falls within these months. Outside the breeding season, individuals disperse widely across the Atlantic. For cruises, understanding these seasonal patterns helps predict the likelihood of encountering the species at sea.

Open Atlantic waters provide feeding habitat, while breeding occurs in rugged upland terrain on selected Cape Verde islands. Nest sites include burrows and rocky cavities. Colonies are not ordinary shoreline attractions, and steep terrain or conservation restrictions can prevent public access. Some breeding sites are located on steep cliff faces or in remote, inaccessible areas, further emphasizing their isolation. These unique environments provide protection from terrestrial predators. Although breeding occurs on land, the species spends the vast majority of its life at sea.

Squid, small fish and crustaceans are reported prey, obtained at or near the sea surface. Detailed diet information remains limited compared with many widespread seabirds. Offshore feeding distributions shift with ocean conditions, so nearby land does not necessarily indicate a regular feeding concentration. Observations indicate prey is often snatched from the surface or just below, sometimes with shallow dives. Like many petrels, they likely utilize olfactory cues to locate patchy food sources. Their diet likely reflects the availability of small pelagic organisms in their specific feeding grounds.

Identification

Its grey upperparts, dark upperwing pattern and mostly dark underwings suggest the Fea's group, but separating it from Desertas and Zino's petrels at distance often requires expert assessment of bill and structure. The Fea's petrel (sensu lato) has a distinctive flight style, with powerful, somewhat stiff wingbeats interspersed with long glides. Key features to note include the short, stout bill and proportionally long wings. Pay attention to overall size and body shape, as this can help differentiate it from other seabirds at a distance.
