You may not be aware of this but across America each year thousands of birds of prey are killed at wind farms. The public perception of wind turbines is that of slow moving blades turning in the wind on a ridge line. The power and danger of the prop design wind turbine is not well understood. Probably the hardest aspect for the public to grasp is that of "tip speed." The killer of eagles and all birds at wind farms is blade tip speed. This is what kills and this is what the wind industry does not publicize or put in their environmental documents.

A series of events on bats look set to be overshadowed by problems affecting the mammals' chances of survival, according to an expert. Anne Youngman, the Bat Conservation Trust's Scottish officer, said wet weather may have hit the breeding season for a second year running. ...On the agenda is a presentation on wind farms in mountain areas of Portugal. Ms Youngman said: "Wind farms were a hot topic at the last symposium. "In Germany, there are turbines above forests and the mortality rate of bats has been found to be high.

One of Spain's last untouched landscapes, the Sierra de Gata in north-western Extremadura, may shortly be inundated with up to 91 wind farms. Ecologists are increasingly concerned about the impact these "parques eólicos" may have on the varied wildlife of the region - and, not least, on its pristine landscapes. Currently, Extremadura is popular with nature tourists, particularly walkers and birdwatchers from all over Europe. For centuries this region was so off the beaten track that many people in the Spanish cities had never heard of it. Now the Sierra is waking up to the 21st century, and it threatens to be a rude awakening.

The plight of these magnificent birds is probably "small change", given the world's present predicaments, but in my book at least, "progress" must not be allowed to fly in the face of conservation. I wonder if anyone will listen....
