Hoary bat numbers declining at rate that suggests species in jeopardy in Pacific Northwest
Science Daily, Oregon State University
The hoary bat, the species of bat most frequently found dead at wind power facilities, is declining at a rate that threatens its long-term future in the Pacific Northwest, according to a novel and comprehensive research collaboration.
Why Wind Turbines Threaten Endangered Species With Extinction
Forbes, Michael Shellenberger
Scientists say wind turbines are the single greatest human threat to migratory bats, which live in different habitats during summer and winter months. Wind turbines have also emerged as one of the greatest human threats to many species of large, threatened and high-conservation value birds, after habitat loss from agriculture. The decline of insect populations may be worsening the threat to endangered bird and bat species. Scientists in Germany say wind turbines appear to be contributing significantly to what it calls the “insect die-off.”
Is Noise Pollution the Next Big Public-Health Crisis?
The New Yorker, David Owen
This New Yorker Magazine article describes how noise does not only have negative impacts on humans but also on animals:
‘They mounted fifteen pairs of bullhorn-like loudspeakers on the trunks of Douglas-fir trees, and, during bird migration in autumn, played recordings of traffic… The recorded sound wasn’t deafening, by any measure; to a New Yorker, in fact, it might have seemed almost soothing. But its effect on migrating birds was both immediate and dramatic. During periods when the speakers were switched on, the number of birds declined, on average, by twenty-eight percent, and several species fled the area entirely. Some of the biggest impacts were on species that stayed. Heidi Ware Carlisle, who earned her master’s degree for work that she did on the project, told me, “If you just counted MacGillivray’s warblers, for example, you might say, ‘Oh, they’re not bothered by noise.’ But when we weighed them we found that they were no longer getting fatter—as they should have been, because fat fuels their migration.”’
Why Climate Activiists Threaten Endangered Species With Extinction
Forbes, Michael Shellenberger
Come on, you might be thinking. Surely there are greater threats to migratory bats than wind turbines? There aren’t. “Wind energy facilities kill a significant number of bats far exceeding any documented natural or human-caused sources of mortality in the affected species,” writes Cryan. Cryan is emphatic on this point. “There are no other well-documented threats to populations of migratory tree bats that cause mortality of similar magnitude to that observed at wind turbines.”
A Climate Conundrum: The Wind Farm Vs. The Eagle’s Nest
The New York Times, Joseph Goldstein
An eagle’s nest on Galloo Island in Lake Ontario has drawn attention to the safety of birds, and accusations of a cover-up have stalled a massive wind turbine project. A judge has questioned the integrity of one of the country’s largest wind farm developers, Apex Clean Energy.

Wind energy is the single largest source of mortality in bats
Water and wings: what Chautauqua County stands to lose
“I know that the temptation is there to have a more financially viable project, but if you can’t do it right, then it shouldn’t be done.” To him, wind energy companies’ drive to create more power — and more money — points to a systemic problem and the environment may pay the ultimate price. “As a species, we really need to stop putting as much focus on money. Obviously, we all need it and rely on it. But it’s not the most important thing in the world. We can’t buy back the bats that are being lost,” he said.
State’s first Article 10 wind project seeks more changes
“The cumulative impact of these wind projects has not been properly publicized or assessed,” he said. “Each project states that their impacts will be ‘minimal,’ yet they fail to address the additional mortality from each new project. … Once these turbines are up, they will begin killing bats for as long as they are operational, and the more that are installed, the worse the problem will become, so we need to consider this very carefully.”
Agencies earn right to challenge wind farm studies
Watertown Daily Times
Both the state departments of Public Service and Environmental Conservation said in letters dated Nov. 2 that they have withdrawn from the particular stipulations due to Apex’s decision not to divulge the knowledge of the nest and the lack of studies to address it.
Wind farm ‘predator’ effect hits ecosystems: study
They found that predatory raptor birds were four times rarer in areas of plateau where wind turbines were present, a disruption that cascaded down the food chain and radically altered the density and behavior of the birds’ prey. In particular, the team observed an explosion in the raptors’ favorite meal, fan-throated lizards, in areas dominated by the turbines.
Wind farm review faces possible extension after eagle nest details were withheld
Watertown Daily Times
Wind farm review faces possible extension after eagle nest details were withheld. “When an applicant withholds information regarding the environmental conditions in a siting application and those conditions are relevant and material to the agencies’ review of the application and negotiation of stipulations and studies to be performed, it raises serious questions about the applicant’s character and fitness.”
Bird populations decrease in areas adjacent to wind turbines – UCC study
Raidió Teilifís Éireann, Ireland’s National Public Service Broadcaster.
He and colleagues surveyed birds at 12 upland wind farms and found that populations of birds were 10% lower in areas close to where the wind turbines were built. Forest species like Chaffinches, Great tits or Goldcrests are the most affected as commercial plantation forests are cleared to make way for turbines and wind farm tracks,” said Dr Fernández-Bellon. “Most people are familiar with the problem of bird collisions with wind turbine blades, but this study highlights how indirect effects, such as the alteration of habitats, can also be important.”
Red light spells danger for bats near wind turbines
“Bats are at a higher collision risk at wind power stations during their autumn migration,” explains Oliver Lindecke, co-author of the study. “Our study indicates that the use of red light signals could have fatal consequences for them as this appears to attract them to operating wind turbines.”
Birds, bats and wind turbines often compete for airspace
The battlefront in this region has become a microcosm of the larger, political tug-of-war over valuable land and airspace that many people agree is probably going to get worse before it gets better.
Wind farms affect small birds too
The Applied Ecologist’s Blog (official blog for Journal of Applied Ecology)
Julia Gomez-Catasus, Vincente Garza, Juan Traba
Due to their low detect-ability and high rate of carcass disappearance, fatality records of small-sized species are scarce and studies based on collision fatality records might be underestimating the impacts of wind farms on these species.
Commentary: Wind turbines around the Great Lakes? A terrible idea for birds, bats
Michael Hutchins, director of the American Bird Conservancy’s Bird-Smart Wind Energy campaign
The rush is on to build scores of large, commercial wind energy facilities in and around the Great Lakes, in Canada and the United States. From the proposed Galloo Island and Lighthouse projects in New York to Camp Perry and Icebreaker in Ohio and Amherst Island and White Pines in Ontario, developers are looking to flood the region with renewable energy. But at what cost?
Wind Energy And Birds FAQ — Part 1: Understanding The Threat
American Bird Conservancy
When it comes to wind energy, siting is everything. The risks are, of course, much greater when wind turbines are placed in areas attracting large concentrations of birds and bats12. When wind energy projects are located in or near major migratory routes, stopover sites, or key breeding or foraging areas, the losses are expected to be great.
Wind farms could be killing 80,000 bats a year, new study finds
A survey of 29 wind farms showed that 194 bats a month were killed, although the figure is likely to be higher because many of the dead creatures would have fallen prey to scavengers.
The research also showed that the risk of bat death increased by 18 per cent for each extra meter of blade length. Some individual turbines were found to kill around five bats a month.
Bird Concerns Lead To Denial of Saskatchewan Wind Farm (Canada)
Citing the protection of migratory birds, the Saskatchewan environment minister announced that the Algonquin Power 177MW project in Chaplin will not proceed.
Hiding Evidence of the Massacre (Scotland and England)
Biased, misleading studies financed by the wind industry are reassuring the public that industrial wind turbines will not only avoid killing eagles but lead us to believe that eagles will actually thrive. Yet, one Australian wind farm killed 7 eagles within a 4 month period revealing that raptors are actually attracted to turbines and that turbines pose a greater threat than previously thought.
Wind energy company sues to keep bird kill data out of public’s hands (Ohio)
Blue Creek Wind Farm (owned by Spanish company Iberdrola) has sued two Ohio state agencies to prevent them from revealing bird and bat kill statistics to the public. The company is claiming that it would be revealing “trade secrets.”

How green is the Wind Industry?
One could believe that the wind industry, with its focus on renewable energy, would also be a consistent champion of wildlife conservation, but it doesn’t always behave that way.
Wind Power and Bats
Of New York’s nine species of bats, the three species of tree bats (red, hoary, silver-haired) do not hibernate in caves or buildings during the winter, but migrate to warmer climes. For these migratory species, the relatively new upsurge in the use of wind energy poses a threat.
Snowy Owls add intrigue to the landscape
KENDALL – Readers have been sending photos of Snowy Owls to Orleans Hub in the last two weeks after sending many last winter when Snowy Owls were here in a historic migration, perhaps the biggest in a half century.
It’s Time for Independent Monitoring of Wildlife Kills at Renewable Energy Sites
Last month, an Oregon-based wind energy company filed suit to block the federal government from releasing information on bird kills at the firm’s 13 wind-power sites nationwide.
Massive Huron County, Michigan Wind Development Planned for Key Migratory Bird Corridor
Under FWS’ current voluntary permitting guidelines, wind energy companies are not required to apply for incidental take permits under the Bald and Golden Eagle Protection Act or the ESA when the project sits on private property. ABC asserts that this is a loophole allowing wind developers to kill federally protected birds with impunity.
Hawk Migration Association of North America’s wind turbine siting policy
The Hawk Migration Association of North America’s official mission is to conserve raptor populations through the scientific study, enjoyment and appreciation of raptor migration. HMANA is concerned about the threat posed by industrial wind energy developments to migrating, nesting and wintering raptors.
