Golden Eagle Breeding Ecology
This project builds on an investigation of Golden Eagle nesting ecology started in 1962 by graduate students of John Craighead. Now in its fourth year, the project focuses on the nesting ecology, movements, and habitat preferences of adult, resident Golden Eagles. As one of three Golden Eagle studies at CBS, it complements our migration study and our research on sub-adult and juvenile eagles. This work adds to one of the oldest datasets on nesting eagles in the country, which is critical to understanding the population dynamics of this long-lived species. This project’s focus on adult eagles is completed, but we will continue monitoring nesting demographics for several years, while expanding the study’s scope to include tracking juvenile Golden Eagles in order to better understand eagle dispersal.
