Golden eagle fitted with Global Positioning System (GPS) backpack
Reports of golden eagle mortality linked to wind energy facilities are cause for concern especially when coupled with the knowledge that golden eagles move great distances between breeding and wintering areas. Mortalities at a particular wind energy facility can consequently affect breeding populations of golden eagles at local and continent-wide scales. Information is needed to understand the distribution of breeding populations of eagles, the level of connectivity that exists among them and where individuals from these populations migrate to in the winter. Information from this study will improve the understanding of the movement ecology and landscape genetic structure of golden eagles in the western U.S.
