Hutchins said studies conducted on bird collisions with aircraft provide insight to wind energy projects. What they find is that birds can see objects coming at them, but they don’t get the same chance to react with turbine blades turning during high winds at up to 175 miles per hour.
“Purdue is involved in trying to look at the genetics of these birds to figure out whether they are local birds that were born and hatched near the Altamont site, or whether they are birds from other parts of the country that are actually migratory,” said DeWoody. He said the numbers are alarming.
A mountain-top wind farm has been scrapped after a judge ruled the spinning blades could kill rare red kites. ... "There are important unknowns in this case."
A recent study of 183 DTE Energy wind turbines found that bird and bat deaths per megawatt is just above average compared to other wind parks in the Midwest.
Many environmentalists who support alternative energy sources are conflicted by the giant turbines' impact on birds. To the human eye the majestic turbine blades make a slow circle as they are set in motion by gulf breezes. The reality is the tips of the blades are really moving as fast as 170 mph, and can lead to fatal encounters for migratory birds and bats.
Wind turbines are known to kill large birds, such as golden eagles, that live nearby. Now there is evidence that birds from up to hundreds of miles away make up a significant portion of the raptors that are killed at these wind energy fields.
“[The wind industry] says their making every effort to be proactive and to reduce birds and bats killed at their projects and they say nobody takes wildlife impacts more seriously than the wind industry.” Hutchins said. “I’m going to challenge that idea.”
This important paper examines how golden eagle mortality at the Altamont wind energy site in California may be having a continent-wide impact on the population. The abstract and supporting data for this report can be accessed from this page.
The Ministry of Environment announced Monday it has denied Algonquin Power’s idea to build a 177-megawatt wind farm with a possible 79 turbines near Chaplin Lake, some 150 kilometres west of Regina.
This paper argues that the methods and data used when estimating effects of offshore wind turbines on seabird population rates and the potential impacts on seabird populations are grossly inadequate. As a result, Environmental Impact Assessments cannot solely be relied on to report risks. The conclusions cited in the paper are provided below.

Iberdrola Renewables, has filed a lawsuit in Ohio to prevent two state agencies from making public what it calls “trade secrets.” The legal action comes after an Ohio bird conservation group, Black Swamp Bird Observatory (BSBO), asked to see bird and bat mortality data for Blue Creek.
The danger wind turbines pose to birds is well known. Less appreciated is that hundreds of thousands of bats are also dying.
In the wake of the release of a U.S. Fish and Wildlife Service migratory bird study, the American Bird Conservancy is calling for an 16-kilometre buffer around the Great Lakes for wind farms. “It is highly problematic to build anywhere near the Great Lakes,” Michael Hutchins, director of the American Bird Conservancy’s bird-smart wind energy program, said Monday. “These losses are just not sustainable.”
If the Scottish Government is truly committed to protecting Scotland’s wild land resource, would it please explain to the rest of us how its much-vaunted Wild Land Map (from which the Stronelairg area mysteriously disappeared on the eve of publication) can have any credibility when the same Government is actively engaged in promoting the destruction of remote upland areas and key wildlife habitats across Scotland?
The American Bird Conservancy (ABC) says a radar study released in July by the U.S. Fish and Wildlife Service (FWS) provides stark evidence that wind turbines on the Great Lakes pose an “unacceptably high risk” to migratory birds and other wildlife.
A wind farm company proposing a project in Northwest Missouri has raised the concern of the Missouri Department of Conservation over potential bird and bat deaths.
“We respectfully request our permit for the Sibley Wind Project be canceled while we work out a solution that will meet everyone's requirements relating to avian studies on the project,” wrote Steve Estes, president of Star Distributed Energy, in a letter to the state Public Utilities Commission. Star controls Sibley Wind Substation LLC, the project developer.
More than €1.5 million has been invested in the white-tailed sea eagle re-introduction programme based in the Killarney National Park, and it was now “at a very critical stage”, the wildlife service added, urging that planning permission for a major upland wind farm by ESB Wind Development Ltd, along the Kerry-Cork border be turned down.
“Right now I could authorize the taking of seven bald eagles without mitigation,” said Beeler, and that is for the entire region. “Golden eagles are set at zero, so we cannot authorize any taking without mitigation.”
And if the federal process works, not a single turbine will ever start slaughtering birds at Dundonnell. ...The (state-based) environmental effects study which gave the project the green light was a joke. Birds in general will be cut down by the turbines. They do end up turning occasionally; indeed when they really get going they can be very efficient bird killers.
