Osprey Conservation Program
Once a rare sight, Ospreys are now seen in Essex County soaring over coastlines, diving into waters to catch fish, and perching on their large nests.
Since 2008, Greenbelt has focused on Osprey conservation by building and maintaining nesting platforms, collecting data, educating the public, and collaborating on research to advance Osprey conservation.

OspreyCam & Blog
Greenbelt’s OspreyCam, located on a nesting platform in Gloucester, has documented the breeding behavior of Annie and Squam for the past eight years. Powered by solar energy, it transmits wirelessly to Lobsta Land Restaurant — and from there, out to viewers around the world.
