Eagles are being protected by a camera system with artificial intelligence called Identi-Flight that spots birds such as eagles and shuts down the wind turbine until the bird has flown away.
Eagles and other animals are threatened by bites from black flies called buffalo gnats. High rainfall causes the flies to hatch early. The huge amounts of fly bites can kill and the flies are so thick they drive the chicks out of the nest where the chicks fall to their death.
