windfarms

Interesting article on wind warms from the US. http://focusingonwildlife.com/massive-bird-kill-at-west-virginia-wind-farm.html The deaths caused in this case were probably avoidable if lights had been turned off, but it wont help the wind-farm industry in they don't adhere to simple measures of mitigation.
The combination of events in this article - time of migration, poor visibility, and lights left on - pose some interesting questions for the UK (given that we are no where near as vast in wilderness as the US). Are these sorts of factors likely to be more or less of a problem at UK wind farms?

Collisions of birds with towers, masts and skyscrapers seems to be much more of a problem in North America than the rest of the world. Median annual estimates are 25 million mortalities from collisions with towers and 1 billion mortalities from collisions with windows. It is obviously possible to reduce the numbers killed, but even these apparently vast numbers have no discernible effect on population trends.
