Range Description

Pterodroma cervicalis breeds on Macauley Island in the Kermadec Islands, New Zealand (c.50,000 pairs in 1988, possibly increasing), with a second small colony recently established on Phillip Island, off Norfolk Island (to Australia) with nests increasing from six in 1994 to 20 in 2005 (Priddel et al. 2010). It bred on Raoul Island, also in the Kermadec Islands, early in the 20th century (Taylor 2000). The rare subspecies occulta breeds in small numbers on Vanua Lava, Vanuatu (Totterman 2009). It migrates to the tropical and sub-tropical north and southwest Pacific Ocean (Heather and Robertson 1997, J. Hobbs in litt. 2009), with a recent sighting off Gau Island, Fiji (Pym in litt. 2008). In February 2010, the rare sub-species P. occulta was photographed, 60 miles from the site of the original specimens, and only the second documented sighting since 1927; a total of 21 individuals were sighted over a three-day period, nine seen rafting before dusk (P. Harrison in litt. 2010).
