Presenter: Patrick Kolar
The northern Diablo Range of west-central California supports one of the largest known breeding populations of golden eagles (Aquila chrysaetos) in the world. This region includes the Altamont Pass Wind Resource Area (APWRA) where collisions with wind turbines constitute a substantial source of mortality for golden eagles and other raptors. From 2014-2020, US Geological Survey (USGS) used a broad-scale survey design to examine spatial patterns in territory occupancy and reproduction by golden eagles based on surveys completed across a 5,170 -km2region includingthe APWRA. This presentation will provide an overview of population ecology ofgolden eagles in the northern Diablo Range and discuss how findings from USGS’s research can helpminimizepopulation-level impacts of wind-turbine collisions and other stressors to golden eagles.
