Bat deaths and Wind turbines - Swedish research, 2004 report

This is an excellent paper with many good references and work.

I particularly appreciate their focus on understanding why the turbine blades "smear-zone" is so deadly to bats; and why bats are attracted to fly close to the turbine blades hunting for food.

We definately need more work on this to discover what changes can be made to turbine structures so they do not function as insect and bat magnets, particularly when located on land on the tops of ridges.
