Who/What in Fact is Killing the Birds?
Wind turbines may perhaps be responsible for the deaths of 33,000 birds per year. In case of electrocutions, the number of these birds is great especially rare birds like raptors. The recent upsurge of interest in wind power has compounded fears about the outcome on birds, which has ultimately led to discussions regarding the wind power industries taking more effort to design bird-caring windmills. Locations selected to set up wind turbines should be ones that are less "birdie." (For statistics about bird mortality and the steps taken by UNEP please visit wind-watch).
Albert Manville, a bird expert with the Fish and Wildlife Service, when questioned to compare the number of birds killed due to wind turbines with those killed by windows, cats and cars stated thus:
“Comparing bird deaths from wind turbine collisions and barotraumas to other sources of mortality — e.g., building windows, vehicles, cats, or communication towers — is akin to trying to compare apples to kumquats. It confuses and muddies the waters. The bigger issue is one of cumulative impacts, specifically what mortality factor will become the proverbial ‘straw that breaks the camel’s back.’ Will it be wind energy, new building windows, oil spills, or other source(s)? We simply don’t know. While wind mortality may presently be relatively low, impacts are all about risk. The blade-caused collision death of one whooping crane becomes an impact to its entire population." (Source: Are wind turbines really that bad for birds?)
