CBF's Osprey Tracking Project allows students and teachers to track three ospreys, one living on Virginia's Port Isobel Island and two on Holly Beach Farm in Maryland, from their home and classroom computers. The page includes lesson plans for teachers and puzzles, projects, and more for students, as well as a link to video of the tagging process. Learn More
