Conservation status of the Atlantic Yellow-nosed Albatross to be assessed on Tristan da Cunha

The Royal Society for the Protection of Birds (RSPB) received a grant last month to assess the conservation status of the Endangered and ACAP-listed Atlantic Yellow-nosed Albatross Thalassarche chlororhynchos on the main island of Tristan da Cunha, part of the United Kingdom Overseas Territory of St Helena, Ascension and Tristan da Cunha in the South Atlantic (click here).

The grant follows on from the ACAP Advisory Committee identifying the need for a census of the main island's population of yellow-nosed albatrosses so that a global population estimate can be made and the species' conservation status can be clarified.

The funding to the level of UK£82 081 comes from the second round of the UK’s Overseas Territories Environment and Climate Fund, known also as Darwin Plus, that was established last year with funds from the UK’s Department for Environment, Food and Rural Affairs (Defra), Foreign & Commonwealth Office (FCO) and Department for International Development (DFID).

Atlantic Yellow-nosed Albatrosses are endemic to the Tristan Group, breeding on all the four main islands as well as on some associated islets.  Population numbers are poorly known on all the islands, because of the difficulty of conducting ground censuses in rugged terrain and among sometimes thick vegetation.  The species has been monitored via a colour-banded population on Gough Island since 1982.  Banding and counts in defined areas have also been undertaken on the main island of Tristan, Inaccessible and around The Ponds on Nightingale Island.

The project aims to undertake a photographic aerial census of albatross numbers on the main island during incubation in September/October 2014 (and perhaps also on Inaccessible Island if logistics allow), as well as work towards improving and expanding the monitoring programme.

Fifteen projects were funded in UK Overseas Territories (UKOTs) in the second round.  Click here for the other 14 Darwin Plus grants funded in the November round.  A Government of St Helena project will study the taxonomic and conservation status of Oceanodroma storm petrels in the South Atlantic.  The Madeiran Storm Petrel O. castro breeds on several islets around St Helena.

The Agreement on the
Conservation of Albatrosses and Petrels

ACAP is a multilateral agreement which seeks to conserve listed albatrosses, petrels and shearwaters by coordinating international activity to mitigate known threats to their populations.
