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.

Pterodroma cervicalis (Sibley and Monroe 1990, 1993, Brooks 2004) was split into P. cervicalis and P. occulta by Imber and Tennyson (2001) and Christidis and Boles (2008), largely on the basis of the latter's smaller size and relative
43 cm. Large, grey-and-white petrel with distinctive white hindneck. Black cap extends to below eyes. White band extends from throat around hindneck. Grey upperparts, upperwing, with black "M" across wings. May have grey half-collar across upper breast. White underparts. White underwing with narrow, black trailing edge, black tip, wider black leading edge distal to carpal joint, short, bolder black bar extending towards centre of wing from joint. Similar spp. Distinguished from Juan Fernandez Petrel P. externa by stronger cap contrast, bolder black marking at leading edge of underwing distal to carpal joint. P. externa has grey nape, but some individuals become almost as white-necked as P. cervicalis.
