Recently my region in Germany had great success in bringing back the red kite bird. Unfortunately a few decided to stay near newly built wind turbines. Thus the turbines are turned off from time to time to protect the seldom animal. This made me wonder which circumstances disturb the red kite and lead to a shutdown of the wind turbines?
There are a few aspects:
- Collision: some birds are better than others at avoiding wind farms, but this is a risk.
- Noise: the noise from the turbine and blades unsettles and upsets animals and birds
- Movement: birds of prey are very sensitive to movement, and the unnatural and fast blade movement upsets their normal behaviour
This can lead to them failing to hunt correctly, problems in rearing young, and even problems in courtship. Read this article and others on the rspb website.
