Wind turbines are harming Europe's largest bird of prey, according to wildlife campaigners.
Nine white-tailed eagles have died in 10 months after flying into turbines at a wind farm in Norway, the RSPB says.
The number of chicks at the site on the Smola islands has plummeted since the wind farm was built.
There used to be 19 pairs of birds breeding chicks, now there is just one pair, and it's thought all of last year's babies have died.
Smola was made an Important Bird Area by Birdlife International in 1989 because it had more white-tailed eagles than many places in the world.
An RSPB spokesman said: "The problem is if wind farms are put in stupid places where there are lots of vulnerable birds and lots of vulnerable rare birds."
"It seems these birds are flying around a lot of the time and they're colliding with the wind turbines and being killed in big numbers."
The company that owns the wind farm says it is doing everything it can to find a solution to the problem.
