The Vulnerable Hawaiian Petrel Pterodroma sandwichensis is endemic to the high Hawaiian islands of Hawaii, Kauai, Lanai and Maui in the north Pacific.  The “big island” of Hawaii supports a small breeding population of around 75 pairs at high altitude on the volcanic peaks of Mauna Loa and Mauna Kea in the Hawaiian Volcanoes National Park.  These birds are at risk to feral cats Felis catus, despite the barren nature of the environment in which they breed in holes and crevices in lava fields.

To protect the Mauna Loa population an eight-kilometre long cat-proof fence, the largest in the United States, has been built by the National Park Service that encompasses 600 acres (245 ha) to keep the cats out.  Construction commenced in 2013 outside the breeding season and has now been completed.

“The specifically designed barrier is more than six feet [1.8 m] high, and has a curved top section that prevents cats from climbing over it.”

It remains to be seen whether the protected Hawaiian Petrels in the absence of feral cats will be deleteriously affected by alien rodents, to which the new fence presumably will not be a barrier.  Rodents have been recorded in the diet of feral cats on Mauna Loa (click here).

The latest issue (No. 28 November 2016) of Project News, the Newsletter of the South Georgia Habitat Restoration Project is now available.  For the last half a decade ACAP Latest News has been reporting regularly on the efforts to rid South Georgia (Islas Georgias del Sur)* of its introduced rats and mice (click here).  The three-phased eradication exercise was completed two austral summers ago and now the task this summer as Phase Four is to assess whether all the rodents are finally gone.

So far no signs of rodents have been seen since the last poison bait drop in March 2015 and reports are now regular on the return to the island of affected birds, such as the endemic South Georgia Pipit Anthus antarcticus and Wilson’s Storm Petrel Oceanites oceanicus, as reported by Project Director, Tony Martin in the South Georgia Heritage Trust’s Project News.

Three New Zealand-trained detection terriers, along with their two handlers, will travel to the island to sniff out rodent sign this summer.  Tony writes “the ultimate rodent detection device is a moist nose on the front end of a highly trained dog”.  Let’s hope the dogs will find nothing and the World’s largest island eradication project can be finally proclaimed a success.

*A dispute exists between the Governments of Argentina and the United Kingdom of Great Britain and Northern Ireland concerning sovereignty over the Falkland Islands (Islas Malvinas), South Georgia and the South Sandwich Islands (Islas Georgias del Sur y Islas Sandwich del Sur) and the surrounding maritime areas.

The Island Conservation Society (ICS) is seeking volunteers for three- to six-month positions in the Aride Island Nature Reserve, Seychelles.  Aride Island is the home of breeding tropical seabirds, including TropicalPuffinus bailloni and Wedge-tailedPuffinus pacificus Shearwaters (click here).

Tropical Shearwaters

Volunteers should ideally possess a degree in a biological sciences and/or useful practical skills or IT skills plus a good level of fitness and the ability to swim.  ICS will contribute UK£ 375 towards international flights and provide free accommodation on 68-ha Aride.  Volunteers will be responsible for their own living expenses on the island.

Apply via the Aride volunteer application form.  Also available: Information for Aride volunteers.

The island is managed as a nature reserve by ICS.  The island’s only inhabitants are the reserve's staff, including the Island Manager, Conservation Officer and rangers.  The Society promotes the conservation and restoration of island ecosystems, sustainable development of islands, and awareness of their vulnerability and vital importance to the planet's biodiversity.

“Please consider that work on Aride can be extremely strenuous, the climate is hot and humid and you are isolated on a small island with only basic first aid”

Paulo Lago. Project Manager of the LIFE Arcipela Garnija Project “Securing the Maltese islands for the Yelkouan Shearwater Puffinus yelkouan” writes to ACAP Latest News with a job offer with BirdLife Malta.

BirdLife Malta is looking for a full-time Project Warden to join its international team in the LIFE Arcipelagu Garnija Project to carry out a range of seabird monitoring and wardening duties at Yelkouan Shearwater Puffinus yelkouan breeding sites in the Maltese islands.

The Vulnerable Yelkouan Shearwater is a potential candidate for ACAP listing.

“BirdLife Malta’s LIFE Arċipelagu Garnija project aims at securing the Maltese Islands for the Yelkouan Shearwater, of where approximately 10% of the species’ global population can be found.  Protection of this local population is important on the global scale, especially with the drastic declines Yelkouan Shearwaters have been facing over the last decades.”

Applications consisting of a cover letter and a CV may be sent to This email address is being protected from spambots. You need JavaScript enabled to view it..

Deadline for applications is 7 December 2016.
