Agreement on the Conservation of Albatrosses and Petrels

ACAP Breeding Site No. 63. Kilauea Point National Wildlife Refuge, home of a Laysan Albatross population

The Kilauea Point National Wildlife Refuge (KPNWR) was established on the Hawaiian island of Kauai in 1985 to preserve its seabird breeding colonies.  It was expanded in 1988 to include Crater Hill and Mokolea Point.  The publically-accessible 82-ha refuge with its steep cliffs is home to the historic Daniel K. Inouye Kilauea Point Lighthouse which sits on the northernmost point of Kauai (click here).  The recently restored lighthouse was built in 1913 as a navigational aid for commercial shipping between Asia and Hawaii.  Half a million people have visited the refuge and its visitor centre and gift shop annually in past years, but recent budgetary constraints have restricted visits to five days a week.

Approximately 115 pairs of Near Threatened and ACAP-listed Laysan Albatrosses Phoebastria immutabilis breed within the wildlife refuge.  Their breeding site is not visible from the public viewing areas, although birds may be seen flying offshore.

Red-footed Boobies Sula sula, Red-tailed Phaethon rubricauda and White-tailed P. lepturus Tropicbirds and Wedge-tailed Shearwaters Puffinus pacificus breed within the refuge, while Brown S. leucogaster Boobies and Great Frigatebirds Fregata minor are regular visitors (click here).  Endemic and Endangered Newell's Shearwaters P. newelli also breed within the refuge in small numbers in a non-public area.  The colony was initially created following introduction attempts utilizing cross-fostering of translocated chicks with Wedge-tails, and has expanded in recent years by the addition of a social-attraction project (click here).

 

"In 2013 there were eight confirmed breeding pairs of Newell’s Shearwaters within the KPNWR and six ultimately fledged a chick.  Auditory surveys carried out at the site by the Kauaʻi Endangered Seabird Recovery Project (KESRP) have also located several more potential breeding pairs and areas of ground-calling activity."

A fence around the perimeter of the refuge provides some protection to its breeding seabirds against the larger predators.  Additionally, the Nihoku (Crater Hill) Ecosystem Restoration Project aims to protect and restore the native environment of Nihoku within the wildlife refuge “through integration of science, natural resources management, and environmental education”.  A 728-m predator-proof fence is planned to enclose 3.1 ha to prepare the Nihoku site for translocatedNewell’s Shearwaters by keeping out feral cats, dogs and rats.  The site would also provide a safe haven for this species if Small Indian Mongoose Herpestes auropunctatus became established on the island (click here and here).

The island’s population of Laysan Albatrosses or Mōlī has been growing since the late 1970s when the first albatrosses returned to Kauai after an absence of many centuries.   With an island total of 271 pairs given for 2008 (click here), the remaining birds are scattered along a roughly 18-kilometre stretch of Kauai’s north shore, from Princeville (c. 40 pairs) to Anahola.  Sixty to eighty pairs attempt to breed on the south-west shore within the US Navy’s Pacific Missile Range Facility Barking Sands (click here).  However, at this last locality the Laysan Albatrosses are a collision hazard to aircraft and so their eggs are removed each year; some of those deemed fertile by candling have been given to foster parents elsewhere on the island, including within the Kilauea Point National Wildlife Refuge, as a conservation measure (click here).
