Polynesian Storm Petrel

Nesofregetta fuliginosa

The Polynesian Storm Petrel (Nesofregetta fuliginosa) is a small, enigmatic seabird of the order Procellariiformes, known for its extreme pelagic lifestyle. Measuring approximately 17-20 cm in length with a wingspan of 40-45 cm, it exhibits a predominantly dark sooty-brown plumage, strikingly contrasted by a diagnostic bright white rump and undertail coverts. Its distinctive flight is buoyant and erratic, often 'pattering' on the surface of the water with long legs conspicuously trailing beyo...

Habitat

This species primarily inhabits remote, predator-free oceanic islands and islets for breeding, often choosing rocky cliffs or areas with dense vegetation. At sea, it is found over tropical and subtropical pelagic waters, far from continental landmasses.

Diet

Its diet consists primarily of small fish, cephalopods, and crustaceans, skimmed from the ocean surface. They are also known to feed opportunistically on oily scraps or discards from fishing vessels.

Behavior

Polynesian Storm Petrels are primarily nocturnal on their breeding grounds, a crucial adaptation to avoid diurnal aerial predators, arriving and departing colonies under the cover of darkness. At sea, they are diurnal, often foraging during the day. Their foraging strategy involves 'pattering' th...

Range

The Polynesian Storm Petrel's breeding range is highly fragmented and restricted to a handful of remote, predator-free islands within Eastern Polynesia. Confirmed breeding sites include islands in the Marquesas, Gambier, and Pitcairn groups, with potential breeding on other small islets across Fr...
