<p class=bodytextfp><font size=3 face=Verdana><span style='font-size:12.0pt'>Having
said the above, we provide here estimates summarized by Erickson et al. (2005)
and estimates reported by the U.S. Fish and Wildlife Service (USFWS 2002a).
Those sources emphasize the uncertainty in the estimates, but the numbers are
so large that they are not obscured even by the uncertainty. Collisions with
buildings kill 97 to 976 million birds annually; collisions with high-tension
lines kill at least 130 million birds, perhaps more than 1 billion; collisions with
communications towers kill between 4 and 5 million based on “conservative
estimates,” but could be as high as 50 million; cars may kill 80 million
birds per year; and collisions with wind turbines killed an estimated 20,000 to
37,000 birds per year in 2003, with all but 9,200 of those deaths occurring in
California. Toxic chemicals, including pesticides, kill more than 72 million
birds each year, while domestic cats are estimated to kill hundreds of millions
of songbirds and other species each year. Erickson et al. (2005) estimate that
total cumulative bird mortality in the United States “may easily approach
1 billion birds per year.”<o:p></o:p></span></font></p>
<p class=bodytext><font size=3 face=Verdana><span style='font-size:12.0pt'>Clearly,
bird deaths caused by wind turbines are a minute fraction of the total
anthropogenic bird deaths—less than 0.003% in 2003 based on the estimates
of Erickson et al. (2005). However, the committee re-emphasizes the importance
of local and temporal factors in evaluating the effects of wind turbines on
bird populations, including a consideration of local geography, seasonal bird
abundances, and the species at risk. In addition, it is necessary to consider
the possible cumulative bird deaths that can be expected if the use of wind
energy increases according to recent projections <o:p></o:p></span></font></p>
