White-necked Petrel

The Juan Fernández petrel is endemic to one island in Chile, Isla Alejandro Selkirk. The breeding population was estimated at 1,000,000 pairs in 1985-86, and there may be up to 3-5 million birds globally. It is threatened by predation from introduced species and, to a lesser extent, habitat loss from introduced herbivores . The World Conservation Union assessed this species as Vulnerable due to its endemic status and threats from introduced predators, and it is on BirdLife's Red-list.

The White-necked Petrel is classified as Vulnerable (VU), considered to be facing a high risk of extinction in the wild.

The White-necked Petrel (Pterodroma cervicalis) is a species of seabird in the Procellariidae family. During non-breeding season it occurs throughout a large part of the Pacific, but it is only known to breed on Macauley Island in New Zealand's Kermadec Islands and the Australian territory of Norfolk Island and Phillip Island. It formerly bred on Raoul Island, but has now been extirpated from this locality. Reports of breeding on Mere Lava, Vanuatu, are more likely to be the very similar Vanuatu or Falla's Petrel, P. More

White-necked Petrel Pterodroma cervicalis 2009 IUCN Red List Category (as evaluated by BirdLife International - the official Red List Authority for birds for IUCN): Vulnerable Justification This species qualifies as Vulnerable because it has a very small range, on two or three very small islands, and it is therefore susceptible to stochastic events and human impacts.

This species resembles the White-necked Petrel, but is slightly smaller at 40 centimetres (16 in) in length and 300–350 grams (11–12 oz) in weight. It has a black cap, white rear neck, dark grey back, wings and tail, and a darker rump. The underparts are white with dark bases to the primary feathers. Like White-necked, the upperparts of worn birds become darker. It is very difficult to separate Falla's Petrel from White-necked Petrel at sea. More

We did however see another White-necked Petrel at sea as well as 2 Kermadecs, 2 Black-winged and a Gould's. More

After an hour or so a WHITE-NECKED PETREL closed upon us from astern, providing a much-needed boost to the prospect of us having a good day. Eventually the wind shifted to the east and we were able to change course into it but our cruise out to the edge of the continental shelf remained uncomfortable. Jaegers dominated the proceedings, including some handsome LONG-TALED JEAGERS, but a steady stream of WHITE-NECKED PETRELS kept our expectations high. More
