Ferruginous Hawk     

Much remains to be learned about Ferruginous Hawk migration and population ecology. Currently, the species is listed as endangered or threatened in several states, as Vulnerable in Canada, and is protected by the Migratory Bird Treaty Act.

A coordinated, international study is underway to provide an understanding of how regional Ferruginous Hawk populations interact throughout the year, and to better understand nesting and winter philopatry of regional populations. Identification of winter and breeding destinations from satellite telemetry will provide information on potential man-caused threats that may limit populations, and hawk survival. Information gained from this project will aid collective recovery and conservation goals for Ferruginous Hawks in Canada, the United States, and Mexico.
