OA 87: Interactions of Juvenile Swainson's Hawks with Wind Energy Facilities During Dispersal and Migration
February 2018 - September 2019
- Department of Energy, Pantex Site
Swainson’s hawks, a large raptor that breeds in the prairies and steppes of North America, both areas of high wind energy development, then migrate to the grasslands of Argentina (an area experiencing rapid wind energy development) in the Southern Hemisphere. Wind energy facilities have been demonstrated to pose threats to avian species through direct mortality and habitat loss. Wind energy development is increasing at a rapid pace throughout much of the developed world. Of avian species experiencing mortality due to collision with wind turbines, raptors appear to be the most vulnerable and may experience proportionally greater population level influences through direct mortality or habitat loss associated with wind energy development. This project is being funded by DOE Pantex. Our study will provide survival estimates, movement data, and habitat use data for juvenile Swainson’s hawks throughout their migrations from Texas to Argentina and back. This will provide important data with which to understand and evaluate hemispheric level risks to the species and other similar long-distance migrant birds.
