nocturnal bird migration near wind turbine

Thermal movie of songbirds migrating in close vicinity to a wind turbine at night (29Sep08). Warblers, sparrows, and thrushes, etc. heading south for the winter. Their short flight calls can be heard. The wind turbine has a height of 125 meters above ground (including blades). Most birds appear to be flying 30-80 meter above ground level. Some appear disoriented and are circling about. This is a dense low-altitude nocturnal flight caused by low cloud ceiling and montane terrain...conditions where wind turbines may be a significant collision hazard to migrating birds. Under clear skies these birds would typically be flying much higher than the wind turbine and collision risk would only be an issue during takeoff and landing.

That is a real problem and they should figure out a way to make it safe for migrating birds

How many bird carcasses were actually discovered around this turbine the next morning? That's the real data you should be posting.

Bastard Global-Warmists. It's a massive farce and damaging nature.

Its the TYPE of turbine thats the problem- exposed blades thros ice, create shadow flicker, make noise, throw blades, etc -

the Cylindrical "maglev" turbine is the way to go to eliminate all the problems of exposed blades-

google it.- its a win for us, and a win for birds.

Honestly, you people care more about BIRDS than HUMANS!? So a few birds get hit? Would you rather suffer from cancer or asthma caused by coal burning power plants? Let me answer that for you, NO! As an asthmatic, coming from Northwestern Indiana, which from 2005 on has been recorded as #85 on the list of areas with the highest air pollution rates! Check the mortality rate of people from those areas, it sucks. I'd LOVE some wind turbines so maybe I can breathe cleaner air.

Shows how dreadfully dangerous these can be to both migratory and sedentary species. thanks for uploading
