President Obamaa s Climate Plan Would Kill Hundreds Of Millions Of Birds And Bats

There are 5 comments on the The Heartland Institute story from Jul 31, 2013, titled President Obamaa s Climate Plan Would Kill Hundreds Of Millions Of Birds And Bats. In it, The Heartland Institute reports that:

A newly published peer-reviewed study reports U.S. wind turbines kill 1.4 million birds and bats every year, even while producing just 3 percent of U.S. electricity.

Oh no, deniers here love the heartless who hate the alternatives to fossil fuels.

It's not the most speciose in their mind. Good grief.

That is pure speculation.

The article does not reference the study that states 14 million dead birds...... I assume they just grabbed the number out of the air....

Hey deniers read this instead:

Comparing bird and bat fatality-rate estimates among North American wind-energy projects†

by K. Shawn Smallwood, PhD


Estimates of bird and bat fatalities are often made at wind-energy projects to assess impacts by comparing them with other fatality estimates. Many fatality estimates have been made across North America, but they have varied greatly in field and analytical methods, monitoring duration, and in the size and height of the wind turbines monitored for fatalities, and few benefited from scientific peer review. To improve comparability among estimates, I reviewed available reports of fatality monitoring at wind-energy projects throughout North America, and I applied a common estimator and 3 adjustment factors to data collected from these reports. To adjust fatality estimates for proportions of carcasses not found during routine monitoring, I used national averages from hundreds of carcass placement trials intended to characterize scavenger removal and searcher detection rates, and I relied on patterns of carcass distance from wind turbines to develop an adjustment for variation in maximum search radius around wind turbines mounted on various tower heights. Adjusted fatality rates correlated inversely with wind-turbine size for all raptors as a group across the United States, and for all birds as a group within the Altamont Pass Wind Resource Area, California. I estimated 888,000 bat and 573,000 bird fatalities/year (including 83,000 raptor fatalities) at 51,630 megawatt (MW) of installed wind-energy capacity in the United States in 2012. As wind energy continues to expand, there is urgent need to improve fatality monitoring methods, especially in the implementation of detection trials, which should be more realistically incorporated into routine monitoring.© 2013 The Wildlife Society

P.S. Not 14 million.
