Predators push treasured birds near extinction on Mt. Kitadake
http://www.asahi.com/ajw/articles/AJ201611070003.htmlPtarmigans, a grouse designated a special natural treasure, could soon be wiped out on Japan's second-tallest mountain because human activity is bringing more predators into the birds’ habitat, researchers said.
In 1981, 150 ptarmigans were found in and around Mount Kitadake in the Southern Alps in a survey conducted by Hiroshi Nakamura, now a 69-year-old professor emeritus at Shinshu University.
Only 20 of the treasured birds were counted there in 2014.
The Environment Ministry is considering capturing martens and foxes, which prey on ptarmigans, at limited locations.
Humans committing suicide.
Deer, martens, foxes, monkeys and crows have emerged in areas where ptarmigans live, although those animals previously were not found in alpine zones.
It is all driven behind the scene by rabbits. I have solution for this. Exterminate martens, foxes, crows, and monkeys.
