This report published by the British Ornithologists’ Union provides an important look at bird migration behavior over water and the potential for collision with offshore wind energy turbines. The authors recommend "abandonment of wind farms in zones with dense migration, turning off turbines on nights predicted to have adverse weather and high migration intensity, and actions to make wind turbines more recognizable to birds, including modification of the illumination to intermittent rather than continuous light, as the most appropriate mitigation measures." An excerpt of the Executive Summary appears below. The full report can be downloaded from this webpage.
