"You asked if the Service is studying the possible cumulative effects of the expanding domestic wind industry on migratory birds and other wildlife. In our letter... dated July 13, 2004, we indicated that the Service is not currently conducting independent studies related to wind energy impacts on migratory birds or bats in the Northeast. Instead, we have been requesting information from project proponents on the temporal and spatial use by migratory birds and bats of commercial grade wind energy sites in the Northeast. However, the wind industry has been generally reluctant to conduct studies and provide such information. Without such pertinent information, and adequately trained field staff, project impacts on migratory birds and bats are difficult to adequately assess, and we are not able to perform our regulatory and advisory roles in licensing domestic wind energy projects on land in the Northeast."
