The moment the endangered white-tailed eagle collides with a rotating windmill at a small wind farm in Hokkaido. The plan for the construction of small wind farms is expected to increase significantly in the future, including more than 7000 certifications nationwide, and experts point out that the impact on valuable birds should be evaluated.
Bird strike, where a bird collides with a rotating windmill of a wind farm, is required to be evaluated in an environmental assessment at a large wind farm with an output of more than 10,000 kilowatts. Not required at power plants.
A research group at the University of Tokushima investigated a small wind farm with a power output of less than 20 kilowatts in Tomae-cho, Hokkaido, and filmed the moment when an endangered white-tailed eagle collides with a rotating windmill.
The white-tailed eagle means that the bone on the right wing was broken and protected by facilities in the way.
The construction plan for small wind power plants is expected to increase significantly in the future, including about 7,500 certified nationwide, and the group should evaluate the impact on precious birds such as eagle and hawk .
Associate professor Yoichi Kawaguchi of the University of Tokushima, who conducted the survey, said, “There seemed to be a bird strike at a small wind farm, but the actual situation is not well understood, and it is necessary to consider evaluation and countermeasures.” It is.
