It would be nice if the idiots at the Associated Press told the truth about migratory birds and wind turbines.

Here's a story in New Scientist magazine that mentions a study in Denmark published last year:

Wind turbines a breeze for migrating birds

* 18 June 2005 * From New Scientist Print Edition.

MIGRATING birds seldom dice with death among the spinning blades of wind turbines. Instead, they give them a wide berth, according to a study of a Danish offshore wind farm.

To see whether the 13,000 offshore turbines planned for European waters would be a hazard to migrating birds, Mark Desholm and Johnny Kahlert of the National Environmental Research Institute in Rønde, Denmark, used radar to track flocks of geese and eider ducks around the Nysted wind farm in the Baltic Sea. The farm's 72 turbines are laid out in rows with their blades 480 metres apart.

Desholm and Kahlert found that the birds flew almost exclusively down the corridors between the turbines, with less than 1 per cent getting close enough to risk collision. The birds gave the turbines an even wider berth at night, sticking more closely to the middle of the corridors. Many also avoided the wind farm altogether. The researchers found that while 40 per cent of flocks in the survey area crossed the wind farm site before construction started, only 9 per cent ventured among the turbines once they were operating (Biology Letters, DOI: 10.1098/rsbl.2005.0336).

I would like to see the Myth Busters take this one on,what exactly are the chances of a boid gettin whacked by a blade?....take a large boid,like a goose and randomly sling it through the path of the blades and see just how many passes it takes to get whacked...use a fake bird of course so as not PO PITA(pains in the a$$es)....bet they would end up calculated the timing just to GET a hit!!!

That just tells us that the birds are smarter and more intelligent than the idiots who think this will really help the energy problem.
