This platform was installed by Bob Brophy, Essex resident, in the 1980s and was the first known active OSPR nest in Essex County in the mid 1980s. In the early years Bob thought productivity was low due to Great-horned owl predation on chicks but eventually the nest produced fledglings and certainly contributed to the beginning of the recovery of OSPR in the Great Marsh.
This platform is located on MA DCR land and was likely installed by DCR. It was visited by Greenbelt in April 2014 and an Osprey was observed on the nest. And it was apparent that it was an old nest that had been in use for multiple years.
These three platforms were built over 10 years ago on abandoned utility poles. Only one has been active; the one furtherest to the north or on the left in the photo. It was active in 2008, 2009 and 2010.
