Wind Energy Takes a Toll On Bird Population- Now There’s Help?

This news is for the fake greens. Greenwashers  Those who push an elitist agenda to the detriment of everything else. Including bird populations. I’ve written on this topic previously. 

Thinking about all these articles that suggest AGW is killing birds. Such as 'warming temperatures" via carbon....  (which isn’t proven) The reality is the god awful monstrosities known as wind turbines are killing birds on a mass scale. That’s demonstrable. Provable. Well documented.
Notice from the article linked above blaming AGW we see this?

“Species that depend on high-elevation forest habitat, long-distance migrants, and coastal breeders are most at risk from climate change
Euronews

Long Distance migrators and coastal breeders- both types of species are greatly harmed by wind turbines- but let’s just gloss over that fact, ok, phony greens?! 

Migratory birds with a giant wind turbine stuck in the middle of their migration paths

I'm a huge fan of birds.
But all that clean, renewable energy comes with a high cost to the nation's wildlife. Researchers estimate that 140,000 to 328,000 birds are killed every year in collisions with the turbines' spinning rotor blades and support towers. The risk to birds is highest at night, when the blades and towers are cloaked in darkness.
Is it clean, green, earth loving energy if it results in mass bird killing?
 That estimate is 140,000 to 328,000 dead birds every year. Year after year. 
Using a medium of 250,000 and to my mind that's low balling the figures. That tells us roughly one million birds would die in 4 years. Two and a half million birds in 10 years. For so called ‘clean green’ earth friendly renewable energy
Massive numbers
On any given night during the peak of the spring migration — from the end of April to the beginning of May — up to 520 million migrating birds are on the wing, says Dr. Kyle Horton of Cornell's famed ornithology lab and one of the researchers involved in the project.
Wing Severed by a Wind Turbine
According to keepers, a wind turbine near the Altamont Pass severed a portion of this 14-year-old golden eagle\'s left wing in 2000, leaving him unable to fly or survive in the wild.

Now researchers at Cornell University in Ithaca, New York, have hit upon what could prove to be a simple way to protect birds from wind turbines. They've used the "signatures" of birds that are visible in raw weather radar data to generate bird maps and live migration forecasts designed to alert wind farm operators to the presence of birds at peak times.
Most are small birds at risk from predators. (Big birds tend to migrate in daylight, although they too sometimes fall afoul of the turbines.)
In other words, since large birds, like the golden eagle shown above will not show up on radar they have zero chance of being saved via this idea
"Our measures are dominated by small songbirds, things like warblers and tanagers, thrushes and grosbeaks — those are the dominant signatures we're getting," says Horton.

It's long been known that migrating birds are easily detected by the Doppler radar systems used to monitor rainfall in the U.S.

 This plan is limited to large flocks of birds.  (Not eagles, hawks etc.,) The plan is dependent on wind turbine operators actually HEEDING the information and either stopping or slowing their wind turbines to save the birds-  
Think they’ll do this? 
Will it cut into their profits? 
Answer that question and you’ll know the answer. 
Fake greens need not think about the reality of this situation and all these bird deaths.

For weather forecasting purposes, of course, the radar signals caused by bird flocks are filtered out. But the Cornell researchers, including Horton and Benjamin Van Doren, a zoologist who recently moved to Oxford University in the U.K., realized that birds' nighttime flights could be used to generate real-time maps that could help save birds' lives.

After working for several years to integrate the signals from a network of weather radar systems across the U.S., the scientists a few weeks ago started posting automated bird migration forecasts and real-time tracking maps at the lab's website, BirdCast.info.

Van Doren and Horton hope wind farm operators will heed the forecasts and maps — which are drawn from 143 weather radar systems across the country — and stop or slow their wind turbines temporarily when large numbers of birds are flying through the area.
 
One solution to the bird-strike problem might be to raise the turbines' so-called "cut-in speed." That's the wind speed above which it makes economic sense to run the turbines. Wind turbines operate more efficiently at the high wind speeds, Horton says, while birds tend to avoid flying on windy nights.

"If we're getting large pulses of [migrating birds] coming through on a handful of nights, then altering their strategies for just, say, five nights versus doing nothing, then it may have a big impact," he says of wind farm operators.

The bird migration maps could also make it possible to switch off some of the lights on tall buildings and communication towers at peak times. The lights on such structures are known to confuse birds flying at night, and result in many fatal collisions, according to Horton.
 
Given the short period of time that the maps and forecasts have been online, it's too soon to tell whether they're having a beneficial impact. But the researchers are hoping for good results. Says Horton, "We really want to see some conservation come out of this, hopefully to reduce some of the mortality."

Large cities, with excessively tall buildings, also kill lots of birds... Like in Toronto
But the street cleaner can clean them up before anybody really sees them.  

Which is another issue the phony greens gloss over- building taller buildings to pack more people into, factory human farming style, present many issues that go ignored.

  1. Wow. Thanks for posting this distressing story. I'm a bird watcher/lover too. In Portland we had a bald eagle couple as "neighbors" for the last few years we lived there. Here in central Ohio we've got a backyard full of birds. I've spotted bluebirds, cardinals, blue jays, a couple of different woodpeckers, titmouse, Northern Flickers, robins, purple finches and the various small birds. Those are what I've seen without even getting my binoculars out. The photo of the golden eagle makes my heart hurt.

    1. Hey Gwen:
      the photo of the eagle hurt my heart as well ( I had to chuckle that you wrote that because it's an expression that I use also- And it feels like a real pain too!)


      I'm smitten with bald eagles (heart thumping)
      Eagles are long lived birds. But all birds are wonderful creatures- I was just out today and saw one Loon, Merganzers, Cardinals, Chickadees, Robins- various wrens and warblers- right now we're lacking our red winged blackbirds- Flickers. No orioles yet either- but noticed the swallows had come back- I don't know what they'll eat as it's so cold and they are bug eaters... as they fly they consume small bugs in the air and as of today there aren't any
      that's going to hurt them :(

      Yes different woodpeckers- I have a woodpecker feather here at my computer- black with white dots on either side- it's a pretty feather

  2. Hi Penny:
    While there is no doubt that the blades of the wind turbines are a threat to birds, I would suggest that is not the major problem that birds and all other wildlife face. The late soil scientist, Dr. William A. Albrecht, PhD, has left his papers to Acres, U.S.A. Acres, U.S.A. has published some of his papers in book form.
    In his papers, Albrecht documents repeatable experiments that show how the health of animals, including birds, is dependent on soil fertility, which is the ability of the soil to produce protein. As the soil fertility declines, he explains and illustrates that higher protein plants can no longer survive in the soil so the woody plants plants move in. People seem to like describing a normal event occurring in nature as the invasion of an invasive species. People are aggressive. I would suggest that it's a mistake to apply a characteristic of people to plants. Any population of animals, such as bees, will experience a declining population as the nutritional value of their food is declining. As the nutritious plants leave the soil so do the animals that depend on them. The final result is extinction of species.
    I find that all the people who suggest they care about wildlife are uninformed with respect to the relationship between nutrition and soil fertility and they no nothing about soil fertility.
    I currently have two years of my time invested in demonstrating that this is the case for the Karner Blue Butterfly. I am growing the plant the caterpillar depends on, Wild Blue Lupine, in clay soil to demonstrate that better soil fertility will, as I intend to demonstrate, better nourish the caterpillar resulting in a more healthy butterfly. I have under $50 invested in my project.
    I also like birds. I shoot them from a distance not with a gun but with a camera. I try to leave the bird undisturbed by my presence.
    Here is a shot I took this winter at the Leslie Spit in Toronto.

    1. Gary, I knew what you meant wrt no vs know.

      The poor health of soil is a huge issue- I understand some about that because I garden-

      One of my other peeves is the spreading of human sewage on crops to grow crops- this is simply disgusting and does nothing to amend soil or grow nutritious food- and goodness knows food has become vastly less nutritious

      "People seem to like describing a normal event occurring in nature as the invasion of an invasive species."

      Yes, invasive species. But are they?
      We've had this discussion in our household on a number of occasions- Since everything moves and changes all the time on earth is a species truly 'invasive'- that topic can be looked at from several directions.

      As for the killing of birds by the wind turbines?
      Many situations/scenarios affect the bird populace, but glossing over the fact the turbines are killing millions of birds yearly- globally, to push a 'green agenda' is intentionally misleading.

      I've seen the snowy owl as well and that's a beautiful image- hope you don't mind if I add it to the post?

      Thanks for sharing your thought and beautiful picture
      Re my work: I do my best here, always

    2. Hi Penny:
      The fertilizer value of manure is connected to what was taken in at the other end. Food of low nutritional value consumed creates composted manure of low fertilizer value. There are connections in nature. Organic matter composted from vegetation grown on low soil fertility creates a compost with a low value as fertilizer. You don't get something from nothing.
      I often say that there are no invasive species, just species better suited than our native species to the current conditions of soil fertility. Instead of fighting a losing "war" against "invasive" species, we should simply increase the level of soil fertility and watch what nature does. Soil fertility determines what plants nature grows in the soil.
      Before I read your post, I was well aware of the consequences of the wind turbines with respect to both birds and on some people living near wind turbine farms. I was not glossing over the consequences but rather pointing out that in my opinion there is a greater threat to all wildlife, including birds, that is ignored.
      You can use the picture of the snowy as you wish.
      Regards,
      Gary

    3. Hey Gary: I am so Sorry, I reread my comment and realize it sounded as if I was commenting specifically on you as an individual.

      That's not the way I meant that at all :(

      I'm referring to this general glossing over of so many problems in order to push an agenda that we are told is "green" and "clean" but isn't.

      Beside the wind turbines (which have blighted my view of the landscape the from the top of the escarpment for miles)

      The Tidal turbines are yet another threat to the fish in that case, but, we're told that's 'green' energy

      Amending soil with as you aptly say 'low value manure' is still another issue- The way it's sold is- well we have all this 'waste' and manure is good for the soil, right?

      Well sure in some instances, but, not in all instances?

      These are complex issues and the simplistic answer provided for mass consumption is so inappropriate.

      Have you ever read Stephen Buhner's work? I just love his books, because he presents interesting perspectives on plants, soil, people etc., and their relationship to one another and the planet

      I added the image of the snowy owl to the post with attribution to yourself,, of course

      Again, apologies for the miscommunication.

  4. Great stuff Penny. I love all the Birds. Years ago my girl and I were sitting in the car eating fries and an Eagle came up looking right into the car just feet away soaring motionless in the onshore breeze. The coolest thing ever.
