Although wind is a green source of renewable energy, a new study has revealed that wind turbines are posing a threat to lives of birds in their vicinity.
Birds colliding with turbine blades are dying.
Researchers were invited by two windfarm owners — one in Samakhiali in Kutch, Gujarat and the other in Harapanahalli, Davangere, Karnataka — to investigate bird mortalities in their farms.
The study found 47 carcasses of birds belonging to 11 species in Samakhiali, among which were threatened species. In Harapanahalli area, seven dead birds belonging to three species were uncovered.
The team scanned a radius of 130 m from the turbines, choosing a spiral path from the base of the windmill. This ensured that all surrounding areas were covered, and no carcass was missed.
