This conference in December 2006 featured presentations by wildlife and environmental experts from around the region. The details of raptor counts, migration paths, song birds and bat populations and potential impacts is frankly comprehensive.
One example is this report on raptor and song bird migration paths and impacts.
This level of research and analysis is being singularly ignored by the wind turbine industry who attempt to downplay its significance - or even dismiss it with "what are a few bird extinctions in the bigger scheme of things?". Unfortunately for the wind turbine industry - their track record on environmental issues reveals that their main concerns are profits and their "green" credentials are a thin veneer.
