Red-footed booby population thriving at globally significant Aldabra Atoll: insights from unmanned aerial vehicle surveys Open
Seabirds are excellent ecosystem indicators and are amongst the most threatened taxa globally. Aldabra Atoll, Seychelles, supports significant breeding colonies of seabirds, especially red-footed boobies Sula sula . The population was surv…

Investigating high pathogenicity avian influenza virus incursions to remote islands: Detection of H5N1 on Gough Island in the South Atlantic Ocean Open
Understanding the mechanisms underlying the emergence and spread of high pathogenicity avian influenza virus (HPAIV) is critical for tracking its global dissemination, particularly via migratory seabirds, given their role in transmission o…

First evidence of mouse predation killing adult great albatrosses Open
Invasive rodents threaten native species in numerous ecosystems, especially oceanic islands. The House Mouse Mus musculus is the only introduced mammal species on sub-Antarctic Gough and Marion Islands. Ample evidence exists of mice preyin…

Cryptic population decrease due to invasive species predation in a long‐lived seabird supports need for eradication Open
Invasive species are one of the greatest drivers of biodiversity loss worldwide, and the eradication of invasive species from islands is a highly efficient management strategy. Because eradication operations require large financial investm…

Mouse eradication is required to prevent local extinction of an endangered seabird on an oceanic island Open
Petrels (Procellariidae) are a highly diverse family of seabirds, many of which are globally threatened due to the impact of invasive species on breeding populations. While predation by invasive cats and rats has led to the extinction of p…

Three new seabird species recorded at Tristan da Cunha archipelago Open
The Tristan da Cunha archipelago comprises three main islands: Tristan, Inaccessible and Nightingale at 37ºS 12ºW, with Gough Island (40ºS 10ºW) the only other temperate oceanic island in the South Atlantic Ocean (Ryan 2007). Tristan and G…

Potential for primary poisoning of a critically endangered endemic land bird during rodent eradication operations at Gough Island, Tristan da Cunha Open
Eradicating introduced rodents from islands restores these communities, but operations must mitigate bait uptake by non-target species to ensure adequate bait coverage, and minimize mortality of non-target species. Ingestion of toxic bait …
