Losses of regional birds hit us hardest. Few people may have noticed that we have been seeing fewer indigo bunting, scarlet tanager, ovenbird or rufus-sided towhee. They live in heavy cover and never have been very numerous. But when we look at typical backyard birds like dark-eyed junco, whose population slipped back 175 million individuals, or the white-throated sparrow, which declined by 93 million individual birds, this hits home.
Any doubt about the numbers of birds can be documented by radar studies of the USFWS under the direction of Jeff Grosse. Hundreds of millions of birds fly over this area and the location of wind turbines in Lake Erie would kill massive numbers of birds.
Golden Eagles are more apt to be killed by wind turbines than other raptors because of their hunting methods, experts say. In California, wind farms in the Altamont Pass area east of Oakland kill an estimated 70 Goldens each year, said Katzner, citing a recent bird mortality study. Nationwide, it's estimated that thousands of birds, including eagles, falcons, hawks, owls, gulls, waterfowl and songbirds are killed by wind turbines.
Testing at wind energy sites throughout the state shows approximately 25 bats and four birds killed every year at each of the state's 420 active turbines ...That puts the estimated kills through June 2010 at some 10,500 bats and 1,680 birds.
Golden eagles and other species are in danger if a proposed Shaffer Mountain wind project by Gamesa Energy USA is constructed, bird supporters said. "If they put wind turbines up, golden eagles are pretty dumb and can't avoid them," Dick, an opponent of the project, said. "It's the wrong ridge to put them up."
A federal agency and Audubon Pennsylvania are among about 40 conservation groups from around the world critical of a wind turbine project that's been approved for Turkey Hill along the Susquehanna River. All the concerns except one revolve around perceived threats 120-foot-long blades on twin turbines would pose to bald eagles, other birds of prey, waterfowl, including tundra swans, and shorebirds that use or migrate through the area.
There are plans moving forward rapidly by PPL Renewable Energy LLC, Allentown, and the Lancaster County Solid Waste Management Authority to construct and operate two gigantic utility-scale wind turbines on top of Turkey Hill in Manor Township. ...Regretfully, there are significant wildlife and environmental problems associated with the proposed Frey Farm Landfill Wind Energy Project. To begin, common sense should dictate that plans are inappropriate to construct two gigantic wind turbines in the middle of such an exceptionally bird-rich location.
The federal government has concluded that building two wind turbines with 120-foot-long propellers atop Turkey Point does not threaten eagles, other raptors or bats. But some birding groups that missed the opportunity to weigh in on the project when public comment was invited believe the environmental impact assessment is flawed.
Lane Johnson said the great blue herons that perch on and near his property in Bell Acres are like an annoying little brother that you wish would go away, but you also feel obligated to protect. ...he spoke during a public hearing Monday night against the proposed erection of a 60-foot wind turbine that would go up about a half-mile away from the herons' nesting spot -- or rookery -- because it might endanger the birds.
Each spring for the past three years, people in my neighborhood buzz about the return of flocks of great blue heron. ...Part of the reason the birds return to Bell Acres is Big Sewickley Creek, a small stream where the heron can fish undisturbed. But how much longer they remain undisturbed is anybody's guess. At the July 20 meeting of Bell Acres' Planning Commission, a proposal was introduced to turn a field about a half-mile from the heron nests into an "alternative energy center."
Turbines already are taking a heavy toll in West Virginia and Pennsylvania. The Pennsylvania Game Commission released a report last spring showing the death rate is highest for bats, which additionally face being wiped out by a mysterious phenomenon called "white-nose syndrome." The evidence has mounted since studies in 2004 showed 1,500 to 4,000 bats annually were killed by the 44 turbines on West Virginia's Backbone Mountain.
An effort to protect both wildlife and wind farm profits will benefit from an agreement by 20 wind energy companies to "avoid, minimize and mitigate" the impact of wind turbines on wild birds and mammals, a spokesman for the Pennsylvania Game Commission said. Unlike Virginia, West Virginia, North Carolina and Canada, Pennsylvania has no regulations for wind farm projects, relying instead on voluntary guidelines without enforcement provisions.
This formal statement was delivered to the Tyrone Borough Council addressing the high risk to Golden Eagles should the Sandy Ridge Wind Farm be permited on Ice Mountain in Tyrone County, PA. The statement was prepared by the National Aviary and other researchers.
Dr. Tom Cade, a professor who preserved the peregrine and is rescuing the California condor, said people making ordinary efforts can help extraordinary birds right here in Pennsylvania. "One problem you folks are facing are these wind turbines proposed to be built on the migration routes," Cade said on the telephone from his home in Idaho. "I don't think there's any doubt that birds, butterflies, bats and bees - they all get hit by those turbines."
A Northumberland County firm has backed off a plan to build wind turbines on South Mountain in eastern Lebanon County. ...But birds and bats got in the way of the plans, said Justin R. Dunkelberger, chief executive for Penn Wind. He explained that the South Mountain site is part of a bird-migration path and is also frequented by bats. "As a wind developer, we have to be concerned with birds and bats," Dunkelberger said. "We want to be responsible developers."
While the open sky is big enough for 400-foot-high wind turbines and migratory birds, animal conservationists are airing their concerns about the threat windmills pose to wildlife. "Any place thinking about installation (of wind turbines) should take years studying the issue," Keith Bildstein, director of conservation science at Hawk Mountain Sanctuary, said Friday. "That is a prescription the wind industry apparently finds distasteful." Bildstein and other local conservationists and bird-watchers say the wind industry fails to adequately study bird migration patterns before wind projects break ground.

To the best of my knowledge, this is the first proposal by any company to site wind turbines on the Kittatinny Ridge or Blue Mountain ...As an ornithologist involved in raptor migrations and hawk watching along the Kittatinny Ridge or Blue Mountain, and author of several books, I am unconditionally opposed to the installation of all wind turbines on this internationally famous, and vitally important, raptor migration corridor.
Two years ago, PPM commissioned a study to learn how many bats could be affected by its proposed wind farm. Biologists hung nets for two nights in 10 locations and caught 138 bats. Cale calculates that if 24 nets -- that's one for each turbine -- were left up through the 14 combined weeks of seasonal bat migration, more than 16,000 bats would be caught. Each net covered an area of about 1,000 square feet. That compares to 66,000 square feet carved out by a turbine's rotating blades. "It's going to be a slaughterhouse," Cale said.
Great egrets -- large, long-legged white birds -- are considered endangered. Terry L. Master, an East Stroudsburg University biology professor, has described Wade Island as the only colony of great egrets in the state. Norfolk Southern Corp. has crossed the Enola freight yards in East Pennsboro Twp. off its list of potential sites for a wind turbine. The reason has a lot to do with nearby Wade Island in the Susquehanna River, a legally protected bird sanctuary for great egrets. "We heard the concerns expressed about the proximity of the bird sanctuary," Norfolk Southern spokesman Rudy Husband said. "We will look elsewhere in our 22-state network."
