Land Bird

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 is a recognised risk for scavenging birds, but is also a concern for generalist feeders. Gough Island, Tristan da Cunha, in the South Atlantic Ocean, has introduced house mice (Mus musculus) that negatively affect the island ecosystem. It is also home to the endemic globally threatened Gough bunting (Rowettia goughensis), a generalist that may be affected by primary poisoning. We presented 26 wild individuals with non-toxic bait pellets and observed their reactions for up to 30 min, or until they flew away. While 23% of Gough buntings did not react to bait pellets, 77% showed some level of interest. Generalist feeders, such as Gough bunting, may also be at risk of primary poisoning during rodent eradication operations.

Invasive Mammals

The house mouse, Mus musculus , is one of the most widespread and well-studied invasive mammals on islands. It was thought to pose little risk to seabirds, but video evidence from Gough Island, South Atlantic Ocean shows house mice killing chicks of two IUCN-listed seabird species. Mouse-induced mortality in 2004 was a significant cause of extremely poor breeding success for Tristan albatrosses, Diomedea dabbenena (0.27 fledglings/pair), and Atlantic petrels, Pterodroma incerta (0.33). Population models show that these levels of predation are sufficient to cause population decreases. Unlike many other islands, mice are the only introduced mammals on Gough Island. However, restoration programmes to eradicate rats and other introduced mammals from islands are increasing the number of islands where mice are the sole alien mammals. If these mouse populations are released from the ecological effects of predators and competitors, they too may become predatory on seabird chicks.

Whaling companies have for some years successfully conducted a whale fishery off the shores of the South Shetlands, Graham Land, South Orkneys, and South Georgia, where the waters of the Antarctic mingle with the South Atlantic Ocean.
