[3] Tuxis Island is closed to people without permission from May to August to protect the many species of birds that nest there.
In 1914, a congressman by the name of Thomas L. Reilly requested a breakwater to be built from the west tip of Tuxis Island to Round Rock, and northwest towards the Madison Wharf.
There are about fifteen species of birds that nest on Tuxis, including geese, egrets, herons, seagulls, ospreys, and oystercatchers.
Fungi can be found here as well, due to the seaspray and tree cover creating a cool, damp environment.
According to the Algonquin, a giant named Odziozo formed Tuxis Island when he scooped up a handful of rocks from the mainland and flung it into the Sound.
