Beginning in 1985, Volunteer Raptor Monitors have helped protect important nesting sites along the Front Range by providing weekly observation reports to OSMP staff throughout the breeding season (February through July). Volunteer raptor monitors conduct site visits that frequently last several hours at a time, observing raptor behavior, nest status, and fledgling activity. This information is utilized by OSMP ecologists to make resource management decisions. Additionally, Raptor Monitors are trained on how to efficiently report any closure violations they observe, further protecting raptor nest viability. Volunteers commit to a minimum of 4 hours per week during the breeding season, and agree to keep nesting site locations and status confidential.
