Wind turbines need to be designed, engineered, operated, and located to be as safe as possible to avian and bat species.
The amount of bird deaths related to oil extraction, coal power plants, mining, resource extraction, petroleum drilling and production, and the climate change associated with burning fossil fuels kills more birds - by many, many, many orders of magnitude - than wind turbines.
If our one and only concern were actually minimizing bird deaths, we would shut down all petroleum and mineral extraction, and associated power plants and supporting infrastructure tomorrow and immediately switch to wind turbines.
If you were genuinely concerned about bird deaths, your first priority would be stopping petroleum extraction, power plants, and the infrastructure associated with burning fossil fuels.
Sadly condors habitat is the same place that turbines work well but that was never considered by those seeking govt $$$ to put up turbines. Just another example of why hovt has no business being in business.
The costs of what you suggest are impossible to justify so much as i like bats (they eat their weight in bugs) we fortunately do not have a shortage of them. Condors on the other hand are nearly gone.
