Buller’s Shearwater breeds only on
Aorangi, Tawhiti Rahi, and five other islets and stacks
in the Poor Knights Islands of New Zealand.
Between 1938 and
1981, after pigs were eradicated from Aorangi, its population
there increased from approximately 200 to 200,000 pairs but it is
unclear whether the population there is still increasing.
Total numbers today are estimated at 2.5 million.
This species nests in
burrows, rock crevices and ledges, often beneath dense vegetation.
Modern fishery techniques, including long lines and set nets, are potential risks for the birds.
