Yeah, in generic raw bird-lives wind-power wins easily. Even turbines designed by Vlad the Impaler aren't going to kill as many birds as the same systematic extraction and burning of fossil-fuels. [0]

> A 2012 study found that wind projects kill 0.269 birds per gigawatt-hour of electricity produced, compared to 5.18 birds killed per gigawatt-hour of electricity from fossil fuel projects.

That said, localized effects are another matter, if someone erects a bunch of wind farms around birds that are in some way vulnerable to them.
