Making a difference: Hutton's Shearwater, an Endangered New Zealand endemic seabird, gets community support

The Hutton's Shearwater Charitable Trust was formed in 2008 to encourage and promote the conservation, research, public education and sustainable management of Hutton's Shearwater Puffinus huttoni.

Hutton's Shearwater is an Endangered seabird endemic to Kaikoura on the mainland of North Island, New Zealand  where it breeds in the Seaward Kaikoura Ranges at elevations from 1200-1800 m in two remaining colonies.  These colonies are under threat from pigs Sus scrofa, Stoats Mustela erminea and other introduced predators, and from natural hazards such as avalanches and earthquakes.

From 2005 to 2008 the New Zealand Department of Conservation led a translocation project whereby nearly 300 chicks were moved from the Kowhai mountain colony to the Kaikoura Peninsula in an attempt to establish a third breeding colony.  The translocated chicks were placed in artificial burrows.

The first record of a bird returning to the translocation colony was in December 2008.  More birds returned in summer 2009/10 at the time that a predator-proof fence was being erected.  The fence was completed in February 2010 and an intensive pest eradication programme was undertaken in June 2010.  Two incubating birds that had been translocated to the site as chicks were found in burrows during the 2010/11 summer as presumed first-time breeders, although both eggs were subsequently lost (click here for more details in the latest newsletter of the Trust).

The Trust has also been investigating the migration of Hutton's Shearwaters by attaching geo-locators to leg bands.  In January 2010, 20 of these devices were put on breeding shearwaters in the Kowhai colony.   Preliminary analyses of 18 recovered devices show post-breeding movements into Australian waters.

The activities of the Hutton's Shearwater Charitable Trust demonstrate how a local community can come together to successfully address a local conservation issue.  What ACAP-listed species could benefit from such an approach?
