Rick Webb's presentation on October 17 at the Energy Virginia conference provides a thought provoking analysis of the costs and benefits of industrial wind energy.

To reiterate, if the SCC chooses to license this project, we request adherence to the monitoring and mitigation recommendations described in this letter and attachments. In the absence of such conditions, we feel this project would pose an unacceptable risk to the Commonwealth’s wildlife resources.

This study focused on nocturnal migration patterns and flight behaviors during the peak periods of passerine and bat migration during fall 2005 at the proposed Highland New Wind Development in Highland Count. Virginia. The key results of our study were: (I) the mean overall fall passage rate was 385 targetsikmh; (2)mean nightly passage rates ranged from 9 to 2,762 targetshh, (3) the percentage of targets passing below 125 m agl was 11.5%; (4) the estimated turbine passage rate of nocturnal migrants passing within the airspace occupied by each proposed turbine was 3.4-24.7 migrantslturbineid during the fall study period; (5) fall migrants flying at or below maximal turbine height consisted of 88% birds and 12% bats; and (6) passage rates, flight altitudes, and visual observation rates of birds and bats did not differ between the two survey sites within the project area.

Unlike in the west, the vast majority of birds likely to be killed at wind turbines in the east are neotropical migrants - which pass through our region mostly at night. Many of these species are already under severe pressure due to loss and fragmentation of breeding and wintering habitat.
