The Ascension frigatebird (Fregata aquila) is
Ascension Island's only endemic bird species. In the past, vast numbers of nesting pairs could be found on both the mainland and the surrounding stacks. However, with human colonisation and the subsequent introduction of rats and feral cats, the population has greatly declined to an estimated 10,000 individuals, all of which have been confined to breeding on the large offshore stack, . For this reason, the species is listed as 'Vulnerable' on the IUCN Red List of Threatened Species. Boatswainbird Island
In 2001, a feral cat eradication programme was initiated on the
Island, led by the Royal Society for the Protection of Birds (RSPB). The last known feral cat was removed from the mainland in March 2004. Seabird re-colonisation of the mainland was first recorded in May 2002 and numbers have increased steadily since. The first species to recolonize were those that previous work suggested were most stressed for breeding space: the Masked Booby (Sula dactylatra), Brown Booby (Sula leucogaster), Brown Noddy (Anous stolidus) and Tropicbird (Phaethon lepturus). The discovery in December 2012 of two pairs of Frigatebirds nesting on the mainland marks the return of all of the bird species to the mainland – a momentous occasion in the history of conservation work on the island. As these birds are colonial breeders, we hope that this marks the start of the Frigatebird regularly being observed nesting on the mainland.
Seabird monitoring is a vital part of the work undertaken by the AIG Conservation Department who carry out annual censuses to monitor population numbers and nesting success. They are also tracking a number of seabird species to build up a picture of where they forage when they are away from the island. Indeed, the department itself was set up in 2001 when a Conservation Officer was recruited as part of the Seabird Restoration Project. Staff numbers have increased since then and there are currently eleven full time staff employed both by AIG and by project grants from, for example, the Darwin Initiative, OTEP and JNCC. The full time team is also supported by volunteers who give up their time to assist with practical conservation work, and other visiting scientists who carry out collaborative research projects on Ascension.
