I can’t believe this is still a topic of discussion but:

It’s a given that anytime we post a story on wind power someone is going to comment that “turbines kill birds,” suggesting that wind power may therefore be unacceptable. Compared to what? Hitting birds with automobiles (along with turtles, groundhogs, and deer)? Birds caught by feral cats? Birds colliding with buildings or phone towers? Quite possibly, a higher mortality will be attached to the transmission wires needed to get the wind power to market. Why, then, do many associate bird mortality only with wind turbines? We hope to get to the bottom of this “death by turbine” myth hole, and point to the factors that can actually be managed though public involvement.
