Surveying for Golden Eagles in California

Patrick Kolar, wildlife biologist at the Forest and Rangeland Ecosystem Science Center, surveys for territorial pairs of golden eagles using binoculars and a spotting scope in the Diablo Range study area of central California. These surveys are part of a larger project looking at golden eagle habitat use and behavior in the Altamont Pass Wind Resource Area and surrounding lands. Golden eagles are vulnerable to collisions with wind turbines, and information about local populations of golden eagles can help natural resource managers and renewable energy developers select sites for turbines that minimize risk.
