This author has no idea what they are talking about- we have extremely high quality data on bird kills from wind farms. Teams of wildlife biologists literally walk the farms everyday identifying kills, and they have other teams that plant fake kills as experimental controls, to accurately quantify exactly the rate that kills are missed, and correct for that. This whole process is required by law, and there are a lot of wildlife biologists that do this work. You cannot operate a wind farm without quantifying its impact on protected species.

  • lutorm 3 days ago

    But it seems that the principal objection to these counts is that birds don't necessarily die on impact but may travel quite far before succumbing to their injuries, so the counts necessarily result in an underestimate of the true effect. Are you saying the area that's surveyed is large enough that this isn't true?

    • UniverseHacker 3 days ago

      I’m certain these studies are able to estimate those other deaths and consider factors beyond just carcasses on the ground, because I am personally close to a biologist that works on this, but I don’t know exactly how they do it. The author here seems to be incorrectly extrapolating research statements on static buildings to windmills, when the latter is much more researched.

      • vouaobrasil 3 days ago

        That seems like something very far from a certainty. Imagine if you were to cite this in a scientific paper: "a close friend of mine does this but I have no idea how they do it". What about this [1]:

        > We show that the use of the ORNIS 1%, the 5% mortality criterion, and potential biological removal criteria are inadequate for providing safe thresholds with respect to the impact of wind turbine collisions on populations.

        From a paper entitled "Mortality limits used in wind energy impact assessment underestimate impacts of wind farms on bird populations".

          Indeed, I am not qualified to answer that question and don’t have the answer, I am not planning on publishing research in this particular field anytime soon.

          I am personally satisfied that this is being done by people that do deeply understand the limitations and capabilities of their work, but I cannot transfer that to you.

          • vouaobrasil 2 days ago

            I do not doubt that people deeply understand the current state of the art, and that they understand those limitaitons. I am 100% in agreement.

            But the fact that they understand the limitations and capabilities in their work has no bearing on the effectiveness of their work when it comes to the specific goal of protecting bird populations. (One does not logically imply the other.)

            • K0balt 2 days ago

              I agree there is a disconnect in pure logic, but I think it is observable that science is often conducted with a goal in mind (and is not then logically pure as a pursuit).

              When the goal is the preservation of a species through the understanding of survival pressures caused by human activity, I think that understanding of the limitations of the state of the art does in fact translate into progress towards actionable understanding of the “ground truth”. This becomes manifest once you factor in the motivations of the researchers, who will use that knowledge to press further study, make new hypothesis, and couch the conclusions of their studies with this knowledge in mind.

              Every advancement in understanding is built upon the knowledge of the shortcomings of previous investigations.

              • UniverseHacker 2 days ago

                Thanks- most people that are researching this are doing so because they care about birds and/or alternative energy- in most cases both.

            • UniverseHacker 2 days ago

              You misunderstood what I was trying to say. I closely know people that do this work with the specific personal goal of protecting bird populations. They are confident they are able to do so, and I have faith in their level of competence based on knowing them well, and also being a scientific researcher in a different but related field. I expect this to carry zero weight as an argument, I’m just explaining where I am coming from.

              I am curious enough that I will ask these details and follow up if I can…

              • vouaobrasil 2 days ago

                > They are confident they are able to do so

                I am certain they are confident they are able to effect change within the limitations that the economic system provides, which is also another difference.

                • UniverseHacker 2 days ago

                  So I asked- and they said (1) when the facility is large enough, which many are, you can randomly sample locations and if they died from injuries elsewhere these will still end up in the sample; (2) they do a lot of separate experiments to measure things like the rate of carcass removal by scavengers which go into the calculations; (3) depending on the type of bird and turbine, in most cases injuries are immediately fatal, and they can quantify this for each case with direct observation.

                  I’ll myself add that presumably the data collected on larger farms can be used as a prior to make accurate inferences on smaller farms.

  • stogot 2 days ago

    After a couple years of data collection, is it still necessary? If we scale up wind farms into thousands, I can’t imagine how many people we’d pay to look for dead birds. Or eventually this will be a drone company

    • UniverseHacker 2 days ago

      It is because they are permitted to operate with a total upper limit of kills for certain protected species. They have to continually monitor, and if they hit the limit they need to seek further approval to keep operating.

pornel 2 days ago

It's annoying that there's interest in these stats mainly as an argument against renewable energy, not from perspective of wildlife preservation. Just those particular birds are precious, not the others killed by other man-made structures, pollution, and habitats destroyed by expansion of agriculture.

I'd like to see not just more precise numbers of birds lost to wind energy, but the environmental and societal costs of not having the wind energy. Fuel extraction and processing has its environmental impact too. Lack of affordable energy (fuel poverty) costs human lives too. How many human lives are harmed to save a bird from a windmill?

  • mcv 14 hours ago

    Yeah, it's kinda weird, the kind of people who are suddenly pretending to be into wildlife preservation. If they were honest about it, they'd also look into bigger bird killers like high rise buildings, powerlines, cars, domestic cats. Also, climate change disrupting ecosystems is unlikely to be good.

    But it's probably a good idea to build wind farms outside major migratory routes.

We simply put up post it stickers where birds usually crashed in our windows. There's way less crashes and dead birds after that.

For folks at home thinking about their windows: Apparently one issue is that windows may mirror the outside environment to birds, appearing as portals to more open-space and trees, especially if you include ultraviolet light which humans can't see and which the glass wasn't designed to pass-through.

So there are a variety of products advertised for home usage that stick to the outside of the window to make it appear more like a barrier, often semi-transparent to us but more-opaque in ultraviolet to birds.

pvaldes 3 days ago

The subtitle is revealing:

[We don't know how much birds kill the windmills so] "This makes it a weak argument against windmills"

"We don't know how much, so it may not happen, or is not so relevant as we think, but is repeated by ideology", is a nasty trick. Nice smoke curtain. Specially when is joined later with:

"it is true that all humanmade structures are technically bird killers, but..."

Either it happens, or it does not happen.

We aren't talking here about a sparrow crashing against a window. What we do know is that carcasses of big raptors, vultures, storks, other birds, and even bats can be found near the windmills basis often, in a distribution that is not aleatory.

Even if we never achieve to calculate an exact value (before the corpses are quietly removed by foxes or companies) we can identify that there is a problem here. As predators are scarce (by definition) and some are endangered, the impact on populations is not negligible.

Killing endangered species is illegal. It does not matter If is "just one" or "just a few" eagles.

  • croes 3 days ago

    So we ban cars?

    So top 3 killers are cats, windows and cars and it doesn’t help if cats only kill small birds and mammals because they basically kill the food of the larger birds.

    Don’t forget tire wear and all the other sources of pollution that endangers any living being.

    And add climate change.

    So why are wind turbines singled out?

    • mrweasel 3 days ago

      > So why are wind turbines singled out?

      Because some people hate the looks of wind turbines, they believe it lowers their property value. To pretend that this is about the birds is absurd, because if it was these same people would target cats as well and they are not doing that and never did.

      People can be amazingly stupid. Some people in my area wanted to prevent the construction of wind turbines as it would destroy the view of the nearby fjord. They strategically forgot to mention that the turbines would be replacing a coal fired power plant (and the open air coal storage). The view is already destroyed, if anything the turbines will actually let you see the fjord and make room for a huge nature area around them.

      There might also be a group of people working in the fossil fuel industry who fear that wind turbines are taking their jobs.

    • mcv 14 hours ago

      > So why are wind turbines singled out?

      Because the oil lobby only objects to windmills, and not to buildings, powerlines, domestic cats, and certainly not to cars. And the oil industry has the funds to control the narrative, and this is a narrative that may get some environmentalists to work for them.

      The counter is of course to widen the discussion to all manmade structures that kill birds, especially glassy high-rises.

    • aziaziazi 3 days ago

      What makes you think turbines are singled out?!

      There’s no point to ban them altogether neither the cats or cars. Consider a range if options between total ban and total unregulation. Thing about traffic code.

      The biologists that took of look at it probably already have propositions like putting them outside of the narrowest migratory corridors or ways to be visible to birds as stickers does on German windows.

    • briandear 3 days ago

      Because we are building wind turbines when there are far better alternatives such as nuclear. We’re also being sold that “wind is better for the environment” when it’s not.

      • croes 2 days ago

        We‘re also being sold nuclear is better.

        Nuclear power plants take a long to build and are expensive in power production and maintenance. Just look at France in the hot summers.

        And that doesn’t include the danger of sabotage and terrorism.

        Didn’t read anything about the fear of russian rockets hitting Ukrainian wind turbines.

        Nuclear power plants are also a SPF. In insecure times decentralization is better.

      • mrweasel 2 days ago

        You will notice that the same people who are against wind turbines are frequently also oppose to nuclear power (and cell tower, highways, factories, farms, forests, high rise building, schools, railroads, new neighbourhoods, pretty much any change that is not to their immediate benefit.

        In many cases nuclear is a better option, but if you want to stand up a few gigawatts of power in two - five years, turbines will let you do that. There's no chance of getting a nuclear power plant operating in a country with no history of nuclear power in less than ten year, and that's perhaps being fairly optimistic. Wind is better than running coal 24/7, which is what you competing against in most cases.

        It could be illegal actually. Even if you install some obstacle near eagle's nest I heard you can be criminally charged. But if you install power lines and eagles kill themselves or you poison some animals and eagles die from eating them you are in the clear

          • throwaway290 2 days ago

            Not really. If you build this window or whatever close enough to eagle base and eagle dies on it incidentally or it is found to be simply disturbed by it you are still criminally liable

            https://www.fws.gov/program/eagle-management/eagle-incidenta... I hope you didn't disturb any eagles lately;)

            (Unless you have a permit. If you are powerline company you are allowed unlimited incidental kills for example. Or if you are wind power company you can apply for a permit for thousand incidental kills or something)

            • lazide 2 days ago

              Having read through that, there is zero chance you could actually violate that doing any sort of reasonable or normal construction.

              Or do you have an example where someone built a house in a reasonable fashion, an eagle ran into it, and the owner or construction company was charged?

              You’d have to build right next to an active nest, or intentionally design the building to be a hazard in an area they were nesting/living. Which goes to my comment.

              • throwaway290 2 days ago

                If you unintentionally violate a law it does not mean you're not guilty. Which goes to my comment. "if a bird kills itself, that isn’t illegal" is simply false per this law.

                Even if the bird doesn't kill itself but simply judged to "can't reproduce" due to your intentional or unintentional action you are guilty.

  • Sloowms 3 days ago

    Counting the carcasses is a very flawed analysis. In cities you rarely find far less carcasses of raptors, vultures and storks. In your analysis this would lead you to making a larger built environment is a good measure to save endangered species. It would even be illegal not to do so.

    • pvaldes 3 days ago

      Is true that we should keep in mind that there is an implicit "at least" 150 eagles killed by just one company. Plus all the other bird species. This value is a minimum estimation.

      Several scientific studies calculate than between 234,000 and 573,093 birds on average are killed by year in USA by windmills. Big and small species. Data points that bats suffer even more than birds. (See Smallwood. 2010. The Journal of the wildlife management 71, issue 8 for example).

      • Sloowms 2 days ago

        I do not understand why you would reply this to my comment. It seems that you are single minded about windmills like a fictional character.

        Without context these numbers mean nothing. Species are displaced by human existence, acting like windmills are the biggest danger and supporting the fossil fuel industry, like you are doing, is not going to help birds or other animals.

        We dont know the statistical extend but we can measure very accurately in smaller areas especially large and endangered birds.

        This is why (in my country) you have to study the local bird population before you get your permission to build your windmills. Something ESI should have done, even if we perfectly knew the statistics of all birds killed by windmills globally.

        > Windmill company ESI Energy LLC, guilty of killing 150 bald and golden eagles in 8 USA states [1][2]

        Read the case. They were guilty of basically not getting a permit. If they got a permit their incidental kills can be thousand+ per project. They are a "least concern" category.

        > But the biggest fallacy in this PR stunt is that outrageous "we don't know, nothing to see here"

        The fallacy is saying this is a concern while not having measurements showing it is a bigger concern than other things like illegal shooting or lead poison or rat poison or power lines or skyscraper windows. If the windmill fighters actually care about birds maybe they could fund these studies. Do they fund these bird studies or just don't want wind energy for whatever reason (like investing into fossil fuels)? If they fund those bird studies why don't we have the measurements.

        Meanwhile there are no permits for killing eagles with rat poison (every death is illegal but who's counting?). Meanwhile every power line operator is given unlimited permit for incidental bald eagle kills. But yes wind turbines, the big enemy of bird lovers.

        We have them around here. In fact, there’s even a Facebook page for a local nesting pair. They mostly eat eels, so water pollution is their worst enemy.

        The thing that often gets raptors, is rat poison. It also kills cats. Rats seem to thrive, no matter what we throw at them.

        It’s generally a good idea to keep cats indoors. I read a statistic that outdoor cats live dramatically shorter lives than indoor ones.
