As raptors migrate in the fall toward wintering grounds and in the spring toward their nesting territory, they exert a tremendous amount of energy, oftentimes covering thousands of miles within a matter of weeks. They navigate numerous borders and habitats and face multiple threats along the way. For scientists, migration serves as the most efficient time to keep tabs on overall population numbers and see if a particular species may be in peril. To this end, HWI has been conducting raptor migration reserach in the west for more than 30 years, utilizing our long-term data to work with wildlife managers on conservation plans.

All of our research sites are open to the public and provide opportunites to learn from our field crew about migration ecology and raptor identification. We welcome and encourage you to visit one of our sites and participate in magnificent show that is raptor migration!
