Big environmental and nature conservation groups like Birdlife, WWF, Greenpeace, Friends of the Earth, and Birdlife support wind energy. Birdlife recently stated that climate change was the single largest threat to birds and wind and renewables were a clear solution to climate change.
Wind farms are always subject to an Environmental Impact Assessment to ensure that their potential effect on the immediate surroundings, including fauna and flora, are carefully considered before construction is allowed to start. Deaths from birds flying into wind turbines represent only a tiny fraction of those caused by other human-related sources such as vehicles and buildings.
A 2012 study carried out in the UK (Pearce- Higgins et al.) concluded that a large majority of species can co-exist or thrive with wind farms once they are operating (Journal of Applied Ecology).
According to the Greening Blue Energy study, "Including both on and offshore facilities, estimated rates of mortality for different bird species range from 0.01 to 23 mortalities per turbine per year" (Drewitt & Langston, 2005). It has been estimated that wind turbines in the US cause the direct deaths of only 0.01-0.02% of all of the birds killed annually by collisions with man-made structures and activities.
