> The amount of birds killed by wind turbines is non-zero but negligible.

Wind turbines don't equally affect all species. Raptors are much more vulnerable to them than are other birds in the area.

When raptors are hunting they are looking down to spot prey, and they have an eye ridge and feathers that try to block out other directions (to keep the sun out so as to not interfere with spotting small prey down below). This means that they have trouble seeing what is in front of them, reducing their chances of noticing that they are going to fly right into something.

Some wind farms are trying to address this by having spotters that keep a watch and when they see a raptor approaching shut down the section of the wind farm the bird is hunting in.

There's a company that has a system for automating this, using cameras and computer vision software to spot the approaching raptors [1].
