UN looks to protect birds from green energy threats [View all]
The global boom in renewable energy is posing new threats to birds say experts.
At the UN climate conference in Bonn, researchers said wind turbines and power lines were a particular problem for migratory soaring birds.
Shutting down wind farms on demand is one of the methods being tested to protect these birds from collisions.
Other ideas being tried include placing highly visible deflectors every 20m on power lines.
