Interactive Osprey Nest Map

Since 2008, Greenbelt’s Osprey Program has been monitoring nesting activity north of Boston. Over this time, we’ve identified more than 130 individual nest sites, including those on wooden platforms installed by Greenbelt and others, as well as on buildings, utility poles, channel markers, and in trees.

Explore our interactive map to discover the location and history of each nest site.
