# Will House Mice continue their attacks on Midway’s Laysan Albatrosses for a third breeding season – and what can be done about it?

*ACAP Latest News* has reported before that introduced House Mice *Mus musculus* have taken to attacking breeding Black-footed *Phoebastria nigripes* and Laysan *P. immutabilis* Albatrosses on USA’s [Midway Atoll](http://www.acap.aq/en/news/news-archive/60-2013-news-archive/1434-acap-breeding-site-no-36-midway-atoll-black-footed-laysan-and-short-tailed-albatrosses-within-a-world-heritage-site?highlight=WyJtaWR3YXkiLCJtaWR3YXkncyIsIm1pZHdheSciLCJubyIsIidubyJd) ([click here](https://www.acap.aq/en/search14?q=Midway+mouse)).

 Mice are the sole rodent and non-native mammal present on the atoll since Black Rats *Rattus rattus* were eradicated in 1996. The new habit, which has resulted in fatalities, was first noticed in just a few areas in December 2015, being recorded again the next breeding season over a much larger area. “When 2016 rolled around we were on the lookout for mice predation. And sure enough we started seeing the same attacks on albatrosses - only this time it was a much greater number of birds and it was much more widespread. It was across the entire island” (click [here](http://usfwspacific.tumblr.com/post/167063752600/midways-albatross-a-new-threat-puts-the-worlds) and [here](https://www.flickr.com/photos/usfwspacific/sets/72157688010783584) for gruesome photographs and night-time videos of mice attacking Laysan Albatrosses).![](https://www.acap.aq/images/stories/acap/Birds/Albatrosses/L/Laysan/Laysan_Midway_mouse_kills.JPG)

 With the 2017/18 breeding season about to start the [U. S. Fish and Wildlife Service](https://www.fws.gov/) “is committed to protecting and conserving the seabird colony on Midway Atoll and finding solutions to this growing crisis.” The service is working with partners to develop a long-term plan address the increasing threat of these invasive predators to seabirds on Midway Atoll.
