Massive wind turbines seem to be killing more and more migratory bats, prompting research into these neglected creatures and efforts to minimize the toll. ...The deaths have led to a flurry of research on migratory bats and their behavior. "The problem with bats and wind energy has pushed a lot of work that wouldn't have occurred otherwise," says Edward Arnett of the Austin, Texas-based nonprofit Bat Conservation International. Indeed, at a January conference in Berlin on migratory bats, wind farms were a dominant theme. Scientists are racing to figure out what brings the bats in contact with wind turbines, and what can be done to save them.

Schemes to monitor the bat population will be carried out all over Ireland this summer amid concerns the population of the endangered species has dropped dramatically. Despite being protected by law, the nocturnal flying mammals are being affected by hedgerow removals, the renovation of old buildings, bridge work and pesticides.

This important collaborative document describes the current research on wind energy and the assessment of impacts on nocturnally active birds and bats.

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.
