Range Description

Procellaria parkinsoni breeds on Great and Little Barrier Islands, New Zealand, where the populations number c.1,300 pairs (E. A. Bell et al. 2009) and 100 pairs respectively, equating to a total population of c.5,000 individuals (Taylor 2000). The estimate of 1,300 pairs on Great Barrier Island is lower than previously thought but probably reflects improved information rather than a decline; however, it is not a complete survey and, although it covers the majority of the island's population, further research is needed to assess the true population size. It once bred in the mountains of the North and South Islands, but had disappeared from the mainland by the 1960s. On Little Barrier, it was abundant in the late 1800s but the population was decimated, mainly by feral cats, until predators were eradicated in 1980. On Great Barrier, the population may be in decline (Bell et al. 2011, E. Bell in litt. 2012). It migrates to the eastern Pacific Ocean between the Galápagos Islands, southern Mexico and northern Peru (Heather and Robertson 1997).
