1446 Tristan Albatross breeding pairs on Gough Island
Last week we completed the challenging and enjoyable task of a whole-island count of Tristan Albatross (Diomedea dabbenena) nests. This is a task undertaken annually by the field assistants on Gough Island. After five days of searching for nests in all suitable habitat, our count came to 1446.
This critically endangered species is endemic to the Tristan island group; however its extinction on Tristan Island by 1900 and negligible numbers on Inaccessible Island means that Gough Island represents the vast majority of the population.
Tristan Albatross are a long-lived species and they breed biennially. Eggs are laid in January and incubated for over two months, hatching in March. It then takes around eight months of steadfast parenting for the chicks to fully develop before most of them fledge around November-December. The critically endangered status of this species is a result of low breeding success due to predation of chicks by invasive mice, and low adult survival caused by long-line fishing mortalities. Together these threats are causing long-term population decline. Our next round-island count of chicks will be in September; only then will we have an idea of the breeding success for this season.
