The numbers are truly astounding."Īlmost all the world's 10,000 ashy storm petrels live off the California coast-half on the island. "Sometimes you'll see the ground moving as mice are burrowing their little tunnels underneath. The question of how best to solve the growing problem has created a decade-long conservation crisis.įederal authorities most recently proposed a controversial solution that would have involved dropping a rodent poison called brodifacoum from helicopters.Ĭritics argued it could have hurt marine life and perhaps even caused an epidemic of dead seagulls in nearby San Francisco.Ĭo-author Pete Warzybok, Farallon Islands Program Lead at Point Blue Conservation Science, said: "Our study provides the latest and most comprehensive understanding of mouse diet and the impacts they're having on the native community-in particular to the endemic arboreal salamander." These plants and wildlife never had to evolve defensive behaviors against rodents in the way mainland species have." Professor Polito said: "Native plants and many animals can't leave the island to get away from the mice.

There are programs on the market that track mouse miles. The study found the mice are highly "omnivorous and opportunistic" diners whose numbers and diets vary dramatically throughout the year due to availability and climate. They also examined their seasonal abundance over a 17-year period-relating it to the availability of native seabirds, salamanders, insects, and vegetation. He explained: "Effectively, mice are what they eat." Professor Polito's team used a technique called stable isotope analysis to trace the chemical signatures of foods in mouse tissues. Lead author Professor Michael Polito, of Louisiana State University, said: "Prior to this research, there was a lack of data on what exactly mice were eating on the island and how their diets changed throughout the year." A plague of house mice is wrecking the ecosystem of the beautiful Farallon Islands of California, according to new research. A 1950s veterinary lab worker smiles at a mouse he holds by its tail as several other brown mice crawl over him.
