CONSERVATION STATUS

Vulnerable

The Juan Fernandez Petrel is a fairly large gadfly petrel that only breeds on Alejandro Selkirk Island off the coast of Chile. After breeding, it wanders widely in pelagic waters of the eastern Pacific Ocean north to the Hawaiian Islands. It forages for squid and small fish that are driven to the surface by Yellowfin Tuna and other pelagic predatory fish. Although the global population of Juan Fernandez Petrels may be 3,000,000, it has been given a conservation rating of Vulnerable by the IUCN because it only nests on one island.

SUMMARY

It has a white face, a black cap extends below the eye, black bill, yellow legs, black toes, and a wedge-shaped tail. Feeds on fish and squid.

INTERESTING FACTS

  • The Juan Fernandez Petrel is dependent on Yellowfin Tuna schools that drive its prey to the surface of the ocean.
  • The word "petrel" is from the Latin word for Saint Peter, and refers the birds' habit of hovering over the water with their feet nearly touching the surface, giving an appearance of walking on water, as Peter is said to have done.
  • This species was previously considered to be a subspecies of the White-necked Petrel, a similar species that occurs in the tropical Pacific and Indian Oceans.
