> Yeah, apparently just paint one rotor blade differently to make it stand out and birds will stay clear [1]

The study you're citing was only studied 4 wind turbines, while the evidence does point towards this working, I wouldn't say that the existing evidence is conclusive. Also, the turbines with the darker blades still killed birds, just less bird than the turbines with standard blades.

Wind turbines don't kill enough birds to be more than a drop in the dead-bird bucket. It's a talking point used by people who were looking for reasons to be against wind turbines, but housecats kill four orders of magnitudes- not 4x, 10,000x- more birds each year.

The percent of human-caused bird deaths due to wind turbines is smaller than the percent of Americans dying in airplane crashes each year, compared to all US deaths each year.

Well judging from your comment it's going to be hard to get your default attitude to change on this. What would change your mind? A popular mechanics article? https://www.popularmechanics.com/science/environment/a247495...

Turbines are bad for birds. Period.

I agree, but I disagree about the claims that were made by the poster whose post I was responding to.
The species of birds that get killed are different. Wind turbines kill bigger birds, cats kill small songbirds.

Both are a non-negligible factor for their respective species.

Windmills generate more than 1% of power. Thus if you scale up the wind turbines by 100x (to cover more than all power generated over the world), they still kill over 100x fewer birds than cats.
seems disingenuous to compare the raw numbers of deaths when windmills still aren’t very common but you want to make them far more common.

not saying i disagree with your point overall but not a fan of that stat

So, paint is cheap. Its not like we're talking a multimillion dollar mitigation. Lets paint some turbines and see what happens.
