Oceanites pincoyae
The Pincoya Storm Petrel (*Oceanites pincoyae*) is a small, enigmatic seabird of the southern oceans, only formally described in 2013, making it one of the newest avian species to science. Measuring approximately 18-20 cm in length with a wingspan of about 40 cm and weighing 40-50 grams, it presents a striking appearance. Its plumage is predominantly a sooty brownish-black on the upperparts, contrasting sharply with a clean white belly and flanks. Distinctive field marks include a prominent w...
This pelagic species primarily inhabits offshore waters and coastal areas, particularly the intricate fjord systems and archipelagos of southern Chile. It exclusively uses remote, rocky islands or steep coastal cliffs for breeding, seeking shelter in crevices or burrows.
The Pincoya Storm Petrel feeds predominantly on small marine invertebrates, including crustaceans like krill, along with small fish and cephalopods. It employs a distinctive surface-feeding technique, pattering its feet on the water to pick prey from just below or on the surface.
Pincoya Storm Petrels are primarily pelagic, spending most of their lives at sea, only returning to land to breed. At their remote breeding colonies, they are largely nocturnal, arriving and departing under the cover of darkness to avoid aerial predators. Their foraging strategy involves distinct...
The Pincoya Storm Petrel is endemic to the coastal waters and archipelagos of southern Chile, with its known breeding range concentrated within the intricate fjord systems of the Los Lagos and Aysén regions, particularly the Chiloé Archipelago. During the austral summer, from November to March, t...
