Cook's Petrel

This species is highly pelagic, rarely approaching land, except to nest and rear young. It ranges in the Pacific Ocean from New Zealand north to the Aleutian Islands. It sometimes can be seen well off the west coast of the United States and well off the west coast of tropical South America. Cook's Petrel feeds on mostly fish and squid, with some crustaceans taken. This bird breeds on offshore islands near New Zealand.

The Cook's Petrel is classified as Vulnerable (VU), considered to be facing a high risk of extinction in the wild.

The COOK'S PETREL is apparently a regular non-breeding visitor far offshore California. Its primary occurrence is over deep waters along the eastern edge of the Pacific gyre, and well beyond the California Current, from perhaps April through November. There is a specimen of a storm-driven birds onshore, and a couple observations of birds "trapped" in the Salton Sea after moving north in the Gulf of California. The primary identification paper for the 'Cookilaria' petrels is Roberson & Bailey (1991). More

the Cook's Petrel pictured in the National Geographic Society guide (Scott 1983), but it has the upperwing pattern of the Pycroft's Petrel (P. longirostris pycrofti) illustrated in Harrison's guide (1983). The crown, nape and back of the Santa Cruz specimen are uniformly dark gray. The color is much darker than that usually depicted for cookii (Harper and Kinsky 1978, Harrison 1983), but the distinctly darker cap typical of P. More

Cook's Petrel breeds from October to April on islands off New Zealand and migrates to the northern and eastern Pacific, where nonbreeding birds occur mostly from April to November in the Peru Current, the California Current, and the North Pacific Convergence (Roberson and Bailey 1991, Spear et al. 1992).

Finally, Oscar Johnson spotted a COOK'S PETREL at the far distant horizon. This would not do. Finally, in desperation, I decided to stop the boat, and lay out a slick that I was pretty darn sure would not work. There simply was not enough wind for the petrels to be flying, or else, they had up and flew the coop. More

Cook's petrel expected to thrive on Little Barrier Island This summer is looking bright for Cook's petrel on Little Barrier Island (Hauturu) with the operation to get rid of kiore completed this week. A boost in the survival of Cook's petrel chicks will be one of the early signs that Little Barrier is rat free. But it will be two years before this can be confirmed when the Department of Conservation will undertake intensive monitoring to check for kiore on the island. More

highlight was a COOK'S PETREL, which was eventually seen well by everyone on board the boat and photographed! Remarkably, the petrel was only about 20 miles offshore, very close for this species. Also, remarkable was the fact that it seemed to stay around the same general area from about 10 am until after 3 pm, allowing us to refind it twice after the initial sighting. More
