I usually get annoyed by people who get all soap-boxy about wind turbines and birds. These same people never seem to care about the birds (and all the other animals) who are killed by fossil fuel power generation.

Do wind turbines kill birds?
Yes - but only a fraction as many as are killed by house cats, buildings, or even the fossil fuel operations that wind farms replace.

That said, it appears they have a path forward for this particular wind farm:

What makes that almost feasible is a recent leap in tracking. Researchers have been fitting orange-bellied parrots with tiny radio transmitters and seeding their flyway with receiver stations, slowly learning the exact timing and route of a journey that was a near mystery a few years ago.

The more precisely engineers know when the parrots are crossing, the more surgically they can pause the machines, the way some birds have begun to tolerate turbines on other sites.

Hopefully they'll get the best of both worlds from this farm.

So the story is not over, and it is not a foregone funeral. A parrot the weight of a few coins has already done the impossible once, crossing an ocean and coming back from the brink. Whether it can also thread its way through a field of turning blades is the question now being written, one migration, and one paused turbine, at a time.

I haven't read this article, but it's been debunked that they cause bird deaths, I had thought.

Just because we are supporters of renewable energy technologies, we shouldn't pretend that they are perfect. No technology is and that is why we're always improving and altering its usage as is happening with this project.

Wind turbines can and do kill flying animals, both birds and bats, though not in large numbers. That is why they have found overseas, for example, that painting one of the blades black helps animals to see the blades better and avoid getting killed.

Thanks for the info! Brilliant to know! I was genuinely asking. I know it's hugely conflated, and co-opted the harm to birds. I'm not saying zero harm, just that the amount of harm caused is conflated in disingenuous ways (mostly from unreliable sources). No energy production is perfect, literally all energy creation has energy loss or bi product, etc. I didn't mean to come across as trying to portray a standard of perfection. Apologies.

And I never thought of you as trying to portray such a standard. We have to work within the confines of the written word only and it can lead to misunderstandings.

Another curious tactic used is to stick a couple of decals (about a metre in diameter each) that resemble open eyes towards the base of the wind towers. This apparently puts off eagles because they don't like to be stared at so they fly away from the towers. I have not seen any studies that completely confirm their effectiveness but I know the staring eyes were being used in Spain a few years ago along with the black blades. by one of the major power companies there.
