The Henry L. Ferguson Museum invites visitors to learn more about the Prehistory, History and Natural History of Fishers Island – and its protected lands.

The Museum offers a wide array of hands-on opportunities and online resources for the education and enjoyment of the Island’s community and its visitors.

The Coastal Forts of Eastern Long Island Sound:
Abandonment, Ruination and Repurposing

Looking beyond the visually compelling crumbling facades of gun pits, the striking through-line of this exhibition is the active repurposing of large sections of these former military reservations by scientists, naturalists and conservationists into nature sanctuaries and, in the case of Great Gull Island, a tern research center.

For the education and enjoyment of the community and visitors, and for the protection of habitat for the Island’s flora and fauna.


Plants and wildlife are fascinating to observe and study.

Fishers Island is an exceptionally beautiful place. We are surrounded by a natural landscape brimming with diverse plants and animals. Without flora and fauna, we could not exist, and the interdependent relationship between people and our environment sustains a delicate balance that must be protected and conserved for future generations.


350 acres of open space are protected by the Museum’s Land Trust.

Explore the diverse ecosystems and wildlife habitats each trail offers. Passing through sun-streaked woodlands, open meadows, coastal bluffs and shaded mossy paths, you’ll see birds and wildflowers, tall grasses, and a variety of trees. You may hear the hoot of a Barred owl, glimpse an egret catching its dinner, or simply experience the stillness of a nature preserve.


A virtual window into the natural world of birds on Fishers Island.

The Museum web cam connects viewers to the intimate life cycle of our osprey neighbors. Watch the unfolding action over time as the eggs hatch, the male delivers eagerly awaited food to the nest, and the female broods the young. Approximately 55 days after hatching, the chicks will fledge with feathers and wing muscles that are developed enough for first flight. We hope that this window on their world will inspire further conservation efforts on Fishers Island.


Learn about the rich and storied history that connects our community.

Thanks to generous, thoughtful donors and Museum leaders with the foresight to recognize how preserving our past helps to guide our future, the Museum holds extensive collections of documents, photographs, and ephemera reflecting all aspects of Fishers Island’s history. We invite you to explore the selected samples available online.
