The research (there's rather a lot of it) shows that wind turbines
kill no more birds than anything else high we put up: cell phone
towers, tall buildings, etc. The count is est. 2-5 birds/turbine/
year. (My own engrg building is only 3 stories but has a glass
mirror skin and kills at least that many birds/yr or more.) The bad
reputation stems from a rather poorly thought-out project in the
Altameda (sp?) valley in CA: the valley has the highest concentration
of raptors of almost anywhere in the US and today would never have
been used as a turbine site.
