Bats are dying as they fly into low-pressure zones around wind turbines. The sudden low pressure causes the air in their lungs to expand and cause tissue damage, called barotrauma. Low-pressure area: most severe immediately out from the blades and decreases as it gets closer to the centre of the turbine. There is also a low-pressure area down the shaft.

Sudden air pressure changes around wind turbines is likely behind the large numbers of migratory bats found dead in southern Alberta, according to a new University of Calgary study. The two-year study found 90 per cent of the studied bats found dead below turbines near Pincher Creek suffered severe injuries to their respiratory systems consistent with a sudden drop in air pressure that occurs near the turbine blades.

Canadian researchers have found wind turbines can kill bats without them actually flying into the blades. ..."An atmospheric drop in pressure at wind-turbine blades is an undetectable - and potentially unforeseeable - hazard for bats, thus partially explaining the large number of bat fatalities at these specific structures," said Baerwald.

Birds are in big trouble in North America. A recent study found 127 species of neotropical migratory birds are in decline. How badly? The Black-chinned Sparrow population has fallen 89 per cent over the past 40 years, the Cerulean Warbler is down 83 per cent, and Sprague's Pipit population has declined by 81 per cent. So drastically have overall migratory bird populations fallen that one scientist who compared weather satellite images over time, found that migrating bird flocks were 50 per cent smaller than they were several years ago. Last week in Washington, Congress began hearings into the crisis and there were calls on the government to boost funding to the Neotropical Migratory Bird Conservation Act.

Governors from several western U.S. states and Canadian provinces met Sunday to discuss strategies for protecting wildlife that roams their region while also capitalizing on immense energy resources. ...The council´s task will be to identify key wildlife corridors and habitats for wildlife, such as pronghorn antelope, sage grouse and bear. The council will also study ways to protect animal habitat in the face of ever-increasing demand for domestic energy development _ both in the form of oil and gas drilling and new construction of solar and wind generation plants _ the building of new infrastructure for the region´s growing population and the effects of climate change.

On June 4, 2008, the Minister of Tourism confirmed the province's approval for the Wolfe Island Wind Project. Premier Dalton McGuinty asked the Minister to step in when the Environment Minister declared a conflict-of-interest on May 29, 2008. Controversy over the Wolfe Island Wind Project centres on the location of a handful of the 86-wind turbines that Canadian Renewable Energy Corporation hopes to build on the island later this year.

Following a study of the movement of birds at a proposed wind farm site, the City of Summerside has reduced the number of turbines planned and changed their shoreline location. ...Two of the four turbines would go on the shoreline of Malpeque Bay, just east of Slemon Park. The site is recognized under an international conservation treaty signed in 1971, known as the Ramsar Convention on Wetlands.

Wellington North should develop local guidelines for development of wind energy projects, its Economic Development Committee (EDC) decided last Wednesday. ...Mr. Taylor said the county regulations failed to address specific setback issues with regard to how far a wind turbine should be located from sensitive areas. "There was little or no reference to bird migration," he said. "They talk about being concerned about being beside our greenlands, but they don't say how far." Concern at the EDC revolves around the impact wind turbines might have migratory bird routes at Luther Marsh. The regulations also fail to address a process for public input on wind developments.

A ban on wind energy projects within 200 metres of the Lake Erie, Lake St. Clair and the Detroit River shoreline is among the many recommendations in the final draft of official plan changes proposed for the County of Essex. Bans would also protect national parks, conservation areas and a host of smaller natural areas, particularly those with endangered or threatened species. The recommendations by the Jones Consulting Group divide the county into four different management areas and requires that proponents show their wind farm proposals won't harm communities or the environment. New policies would protect "heritage resources and significant cultural heritage landscapes." The visual impact of turbines, that could be 120 metres high, has to be weighed for the impact on scenic viewpoints and landscapes.

Opponents of a 410-million dollar wind turbine farm on Wolfe Island won't rule out a court appeal to stop the project from spinning ahead. They've been trying to get the province to impose a more rigorous environmental assessment. But so far, no luck. That means "Canadian Hydro" is moving full speed ahead with plans to start installing the turbines this summer. Newswatch's Stu Hay has an update. "Disappointed" is the only word Wolfe Island resident Sarah Mcdermott can come up with to describe her feelings. Wolfe Island is slated to become a giant wind-farm this October... She was hoping that the environmental impact of the project would be scrutinised more than it has been... But she's been told that's not going to happen.

The Ministry of the Environment has turned down requests from Wolfe Island residents seeking a more detailed study of the effects of a proposed wind-power project in their community. In a letter dated March 27, citizens learned that the ministry had declined their request to require Canadian Renewable Energy Corporation to prepare an individual environmental assessment before the firm's 86-turbine wind project is allowed to proceed. ...Her decision to quash the individual environmental assessment - applied to large projects with potential environmental impacts - leaves residents feeling that the province is pushing the project without adequately addressing their health and environmental concerns. Many saw the environmental assessment as their best chance to have their concerns addressed before construction began.

Two years after B.C. Premier Campbell announced a "historical land use agreement" that was intended to protect Canada's Great Bear Rainforest, it remains unlegislated. Although the land use agreement was supposed to establish new conservancy boundaries, new large scale industrial proposals are planned within these same areas-leaving the world renowned Great Bear Rainforest under threat once again. ...The Provincial Government and the Canadian Wildlife Service are conducting an environmental assessment for a massive wind farm, which will include a 150km high power transmission line that extends through four other Great Bear conservancies.

Whooping cranes, one of the world's rarest birds, have waged a valiant battle against extinction. But federal officials warn of a new potential threat to the endangered whoopers: wind farms. Down to as few as 16 in 1941, the gargantuan birds that migrate 2,400 miles each fall from Canada to Texas, thanks to conservation efforts, now number about 266. But because wind energy, one of the fastest growing sources of renewable energy, has gained such traction, whooping cranes could again be at risk - from either crashing into the towering wind turbines and transmission lines or because of habitat lost to the wind farms. "Basically you can overlay the strongest, best areas for wind turbine development with the whooping crane migration corridor," said Tom Stehn, whooping crane coordinator for the U.S. Fish and Wildlife Service.

The Unamaki Institute of Natural Resources, based in Eskasoni, is calling for consultations with the island's First Nations communities. The Pitu'paq committee, comprising Cape Breton's municipalities, First Nations communities and government agencies, has called for a full panel federal environmental assessment and independent Mi'kmaq environmental assessment. Laurie Suitor, intergovernmental relations adviser with the Unamaki institute, said Lisi, who is also Cape Breton Explorations chief financial officer, has yet to sit down with aboriginal groups to discuss the company's plan for 44 wind turbines and a hydroelectric plant powered by water from Lake Uist. "Unfortunately, he hasn't followed up on that to date," Suitor said, adding that an extensive federal review of the project is needed to sort through any potential negative environmental impacts that may arise. "A full panel federal environmental assessment would bring a lot more scrutiny to the project."

An alpine wilderness in northern B.C. that's critical habitat to a herd of threatened mountain caribou is being proposed as the site for hundreds of industrial wind turbines. Aeolis Wind Power Corp. based at Sidney on Vancouver Island has provided the B.C. Environmental Assessment Office with draft terms of reference for its 1,000-megawatt Hackney Hills wind farm, about 45 kilometres northwest of Hudson's Hope. ..."Global warming is being used as a Trojan horse to justify all manner of high-impact energy projects, and Hackney Hills is a prime example," said Wayne Sawchuk, an award-winning Peace Valley conservationist and member of the Canadian Parks and Wilderness Society board.

The need for proper setbacks in Chatham-Kent between wind turbines and homes and natural settings was voiced loudly Tuesday by Chatham businessman Harry Verhey. Verhey told Chatham Sunrise Rotary Club members - of which he is a member - that he isn't challenging the use of wind turbines, but is convinced there is an urgent need to determine setbacks that are right for the municipality. "The recent proliferation of industrial wind projects will have a negative impact on the community," he said. "The massive size of industrial wind turbines conflicts with the scale and character of the Chatham-Kent landscape." ...Verhey said ads run in local papers by the proponents of wind farms aren't enough - "for the most part the public is unaware of turbine developments and locations."

Massive commercial power developments are being considered for existing and planned conservancy areas on the B.C. coast, raising doubts about a landmark multi-stakeholder agreement designed to bring peace and economic certainty to an area known as the Great Bear Rainforest. "Premier Gordon Campbell is completely going back on his promise to protect this coast," charged Ian McAllister, the award-winning author and conservationist who coined the term Great Bear Rainforest and who now works under the banner of Conservation Pacific. "This isn't world-class, this isn't a model we'd want to have any other region on the planet follow."

Wind generating companies competing to place turbines on mountain tops are also competing with wildlife seeking secure habitat. Along with construction traffic and noise, new access roads allowing recreational vehicles passage into previously untouched woodlands, rotor noise, and visual noise from the shadows of turbine blades could also have an impact. "It's a question that we don't have all the answers to," said Nette. "There is a big unknown there. I'm not sure we are giving it adequate consideration." Wildlife biologist Bob Bancroft is looking to answer that question by researching studies done in northern areas of the United States to learn about the impact wind turbines there are having on wildlife species, including moose.

Alternative power is all the rage but even a magic bullet can draw blood. Dave Bidini visits Ontario's bucolic Wolfe Island, where an Alberta firm wants to build a $410-million wind farm, bigger than any now operating in Canada. Many residents are bitter - their home is a major stopover for species that migrate in the dark, 'when you can't see the birds getting chopped out of the sky'

County council will be spending approximately $10,000 more on its wind power study but not all members were pleased with that stance. The extra $10,000 will assist in predominantly helping to further study the migration patterns of birds and bats to ensure they aren't impacted by proposed wind energy projects, an issue which arose during public meetings ...Amherstburg Mayor Wayne Hurst believed the money would be well spent. He believed that the county has to ensure they are doing as much as they can to make sure that due diligence is being met. Essex Deputy Mayor Richard Meloche believed "our research is too important not to spend the additional money." ..."These turbines will be here for years to come and site planning is extremely important. ..."We strongly believe buffer zones must be determined for the sensitive wildlife areas such as Point Pelee, Hillman Marsh and Holiday Beach. There are important long-term environmental and tourism impacts to consider for Essex County."
