For some islands (e.g. New Zealand’s [Antipodes](https://www.acap.aq/en/news/news-archive/60-2013-news-archive/1358-acap-breeding-sites-no-23-antipodes-island-new-zealand-supports-seven-acap-listed-albatross-and-petrel-species?highlight=WyJhbnRpcG9kZXMiLCInYW50aXBvZGVzJyIsIm5vIiwiJ25vIl0=)) final results of eradication attempts are still awaited. Plans are being made to rid the UK’s [Gough Island](https://www.acap.aq/news/news-archive/60-2013-news-archive/1322-acap-breeding-sites-no-11-gough-island-south-atlantic-hanging-on-against-the-onslaught-of-its-killer-mice?lang=en) and South Africa’s [Marion Island](https://www.acap.aq/en/news/news-archive/60-2013-news-archive/1371-acap-breeding-sites-no-27-sub-antarctic-marion-island-a-research-laboratory-for-albatrosses-and-petrels?highlight=WyJtYXJpb24iLCJtYXJpb24ncyIsIm5vIiwiJ25vIl0=) of their introduced House Mice *Mus musculus*over the next three years.

News is now to hand that the French have commenced a year’s research on the feral cats, Norway Rats *Rattus norvegicus* and House Mice on [Amsterdam Island](https://www.acap.aq/en/news/news-archive/60-2013-news-archive/1429-acap-breeding-sites-no-37-ileamsterdam-only-home-of-the-amsterdam-albatross?highlight=WyJhbXN0ZXJkYW0iLCJhbXN0ZXJkYW0ncyIsIm5vIiwiJ25vIl0=) in the southern Indian Ocean ([click here](https://acap.aq/Http://saintpauletamsterdam.blogspot.co.za/2017/12/mammiferes-introduits-une-nouvelle.html)). Population estimates of rodents will be made, and cats will be monitored with camera traps. ![](https://acap.aq/images/stories/acap/Islands/Amsterdam Island Thierry Micol s.jpg) Amsterdam Island, photograph from Thierry Micol According to the article, the Norway Rat is suspected of being a carrier for the bacterium *Pasteurella multocida*, responsible for avian cholera which kills chicks of the [globally Endangered](http://datazone.birdlife.org/species/factsheet/22728372) Indian Yellow-nosed Albatross *Thalassarche carteri*, on the island, of which two- thirds of the world population breeds on Amsterdam’s Entrecasteaux cliffs. Rats will be sampled for *Pasteurella.* ![](https://acap.aq/images/stories/acap/Birds/Albatrosses/I/Indian_Yellow_nosed/Indian Yellow-nosed Albatross - DEMAY JEREMY s.jpg) Indian Yellow-nosed Albatross with its chick, photograph by Jeremy Demay The intention is for the research to inform planning for the simultaneous eradication of the three alien mammals.
