They also stop or reduce turbine speed during peak migration season, and scientists have found that painting one of the blades a dark color prompts the birds to fly further away from the turbine.

They do kill a lot of birds though, and bats. An absolute fuckton of bats. My partner did turbine strike studies in college, and said that the number of bat deaths is really disheartening. Bats in my area like to find the tallest "snag" to roost in... Guess what a wind turbine looks like to them...
