CSG Project Studies

We began studying the eastern North American population of golden eagles in 2005 to understand their ecology and movement behavior in relation to wind energy development in the Appalachian Mountains. Since 2006, we’ve telemetered 100 eagles in 12 Eastern states.

As of 2020, the Chesapeake Bay Region has become a focal point for bird-aircraft collisions, at both civil and military airfields in Virginia and Maryland. The purpose of this project is to understand bald eagle behavior to reduce eagle-aircraft strike hazard in the region.

Lead poisoning is an important cause of mortality and morbidity in bald eagles. The goal of this study is to identify strategies to reduce eagle moralities from lead poisoning. To reach this goal, we will develop a compensatory mitigation strategy.

Bald Eagles in the Upper Midwest regularly use upland areas away from water, which results in eagles encountering threats such as wind turbines, power poles and power lines, vehicles, and carrion contaminated with lead bullet fragments.

The overlap between wind energy and eagles has resulted in notable negative turbine-eagle interactions. The goal of this project is to create spatially explicit risk models to aid managers in minimizing negative interactions between eagles and wind turbines.

We used telemetry to produce highly detailed data on how and where Bald Eagles fly and use airspace. We analyzed these data in the context of topography , weather, and land cover to understand what environmental conditions may put eagles at risk from wind turbines.

We are capturing ravens and attaching GPS-GSM telemetry units to track their movements. This will provide data that will allow wildlife managers to focus their conservation efforts and funds to best conserve desert tortoise through management of raven predation.

In early 2020, CSG partnered with the National Park Service and Alaska Department of Fish and Game to examine the annual movements of pre-breeding golden eagles, quantify the potential drivers of those movements and identify potential anthropogenic threats to these birds.

Risk from behavioral changes by or mortality of eagles in response to turbines is especially poorly understood because there has been little research on this problem for Bald Eagles in the Great Plains. Our primary method for studying Bald Eagles is telemetry.

We are distributing non-lead ammunition to hunters in southeast Wyoming. We are then quantifying the number of game animals harvested with non-lead ammunition and finally, estimating the reduction in golden eagle moralities.
