Speaking in German numbers:

Wind Energy kills arround 100.000 Birds a year. Lovely furrballs arround 20.000.000 (likely more) Glass plates like windshields, Windows etc. Arround 100.000.000 So yeah pretty minor.

That wind turbines kill birds is entirely sensationalized and overstated, absolutely.

Birds die from way more sources, like feral cats and flying into glass windows. Looks like someone else posted the source.

Things have gotten better since we noticed that birds recognize the turbine blades more easily if 1 of 3 of the blade are painted a non-white color.

Don't think we've really done anything with cats and windows to mitigate those issues

The problem is its actual history.

Windmills did kill way too many birds

• when they first built at Altamont pass, a natural constriction on a major migratory bird route
• when they used open lattice towers, which present tons of tempting roosting spots
• seems like at least one more major factor.

But this was in like the 1970s and they paid attention. Since then, wind turbines kill effectively zero birds, but it’s a huge problem when there’s an actual grain of truth that conservatives can grab onto and never let go

Edit: apparently still in production despite the poor site, but it looks like they cut bird fatalities in half and are looking at newer turbine designs to be safer. I guess the real lesson is don’t build in a mountain pass constricting a major Migratory bird route

I don't honestly know.

I don't see how they could kill birds anymore than trees do. Birds have pretty good eyesight in many cases better than humans I can't reasonably see why wind turbines would be any more of a threat than any other structure natural or organic.

Well they're not zombies, since they actively hate the concept of brains.
