Osprey Monitoring & Sightings
Where are Osprey Nesting?
For more than 15 years, Greenbelt has been dedicated to Osprey conservation through the construction and maintenance of nesting platforms, data collection, public education, and collaborative research efforts aimed at protecting this once endangered species. Volunteers submit their sightings online, and the most recent sightings are displayed in real-time.
