Are wind turbines a hazard to wildlife?

Wind farms are a very benign technology and generally have very little impact on the environment. However, wind turbines, like all man-made structures do present a collision risk to birds and habitat can be lost during construction if the wind farm is not sited appropriately. The risk to birds and other animals and plants is carefully considered during the planning stage of a wind farm. This includes an analysis of bird flight paths and species populations as well as careful investigation of any native vegetation. No rare, threatened or endangered birds or bats have been killed by wind turbines in Victoria. Mortality rates for common bird species are estimated to be 1 to 2 birds per wind turbine per year. This figure is insignificant in comparison to bird losses as the result of habitat loss from land clearing, the predation by domestic cats, and the collisions with cars along our roads.
