> The most common species found were willow ptarmigan (Lagopus lagopus), white-tailed eagle (Haliaeetus albicilla), common snipe (Gallinago gallinago), hooded crow (Corvus cornix), and meadow pipit (Anthus pratensis) (Table S1). Eagles are large conspicuous birds and will therefore often catch the attention of passers-by. Ptarmigan are often found near the turbine base as they are suspected to collide with the actual tower
This disproves my assumption that many of the collisions were with nighttime migratory birds (maybe that is buildings?). I hope this simple fix applies to all locales and is not specific to Norway.
Last night I watched an episode about Eagles on PBS NOVA. They said predatory birds like eagles are constantly looking down and they also have a ridge above their eyes to block the sun. They basically don’t look up, maybe the white looks like clouds so they don’t think they can run into it.
It’s a pretty cool episode. They use eagle watchers to turn off turbines when an eagle gets too close but the human can’t see in the direct sun. They built a robot with a 360 camera and 2 cameras that rotate to find eagles. It worked much better than a human.
