2017 Osprey Census Summary

  • Number of active nests: 105
  • Number of fledglings: 122
  • Number of housekeeper nests: 7
  • Total osprey on island: 332
  • Number of volunteers: 42
  • Number of volunteer hours: 1,950

Ospreys are a signature species for Martha’s Vineyard. They represent renewal, triumph over hardship, and demonstrate that it is possible to bring a bird back from a dangerous decline. These iconic birds are easy to see, breed on the Vineyard, and are a beloved symbol of the island.

Today, more than 80 nesting pairs of osprey grace the island during our spring and summer seasons and migrate south for the winter. Intense efforts by Felix Neck staff, researchers, and volunteers have led to their current success.

Get Involved

While much is known about these birds, research and monitoring efforts continue to be necessary to ascertain population trends; install, maintain and manage nesting platforms; and learn more about their food resources, predation and migration patterns.

Island resident and Felix Neck volunteer Dick Jennings, with the help of other volunteers, has been managing a yearly osprey census. To accomplish our research and monitoring goals, we are hoping to expand our Vineyard Osprey Monitoring Program.

But we need your help to make this happen! Your support in the form of funding for equipment or volunteering to be part of our citizen science program is greatly appreciated.

About Ospreys

Also known as fish hawks, ospreys are raptors that survive on a diet of 99 percent fish. Every spring and summer, they can be found across the Commonwealth feeding in reservoirs, ponds, bays, and wherever else there are fish to be caught. Learn more >

History of Vineyard Ospreys

When Felix Neck Wildlife Sanctuary opened to the public in 1969, the island had just two pairs of nesting osprey. The causes were numerous, but a major threat to the species was the pesticide DDT. Once it was banned in 1972, the hope was that ospreys would return.

On the Island, osprey populations remained low. Sanctuary Directory Gus Ben David quickly ascertained that the problem was with the availability of nesting sites. Birds were nesting on telephone poles and their nests were being removed by utility staff.

Ben David began a program of installing nesting platforms at locations across the island. The first platform was erected at Mink Meadows and through the years more than 160 nesting platforms have been erected. The most recent was installed at the outlet of the Tiasquam River on Tisbury Great Pond in the fall of 2014 though a cooperative effort between a private land owner, Ben David, and Felix Neck staff.
