The growth of wind power, if undertaken with reasonable care, should pose no risk to any particular bird species in Canada, according to a new peer-reviewed study. The study also suggests that highly publicized bird mortality figures out of the U.S. and Europe could be on the high side.
“Canadian Estimate of Bird Mortality Due to Collisions and Direct Habitat Loss Associated with Wind Turbine Developments” [PDF] was one of several studies undertaken as part of special issue of the journal Avian Conservation & Ecology that focused on the impact of human activities on the mortality of birds in Canada.
The researchers did find that, on average, a wind turbine in Canada results in 8.2 bird deaths per year, and they estimated that a 10-fold increase in installed wind capacity in the next 10-15 years “could lead to direct mortality of approximately 233,000 birds/year, and displacement of 57,000 pairs” resulting from habitat loss.
When the environmentalist charge their electric vehicles do they think about the birds that were killed to provide the power they are using. I will bet not.
