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
In 2013 and 2014, Greenbelt collaborated with leading Osprey researcher Dr. Rob Bierregaard to study Osprey migration using
small solar-powered transmitters. In total, four transmitters have been deployed but only one of those Osprey survived - a male named Flow, hatched in 2014. Flow migrated to Cuba in 2014 and
stayed there until spring 2016, when he came back to Essex County and then returned to Cuba in fall 2016. In the fall of 2017, after spending his summer in New England, Flow's
journey ended on his migration south, where predation was the likely cause of his death in Maryland. View his tracks in the map below.
Hunt by flying high above relatively shallow water to search for schooling fish. Once prey is spotted, Osprey will hover beating its wings, then quickly dive down and sink its talons into
the water and into the fish.
Once in the air, the osprey will position the fish so it’s facing forward, allowing for it to be more aerodynamic for transport back to the nest.
