Watch closely as you hike through the swale. You may catch a glimpse of a fleeing fox!
Seventeen species of terrestrial mammals were identified on Fire Island during surveys conducted in 1974.
In the mid-1970s, eastern cottontail rabbits (Sylvilagus floridanus) were abundant throughout the Seashore. Red foxes (Vulpes vulpes) were very common. Raccoons (Procyon lotor) were far less numerous. The white-footed deer mouse (Peromyscus leucopus) and meadow voles were abundant, and muskrats (Ondatra zibethicus) and Norway rats (Rattus norvegicus) were numerous on both Fire Island and on the mainland at the William Floyd Estate. Squirrels were restricted to the mainland.
Other common species identified in the survey included the masked shrew (Sorex cinereus), short-tailed shrew (Blarina brevicauda), and weasel (Mustela spp.). Weasels and mink were secretive but locally common predators throughout the seashore in the mid-1970s.
The little brown bat (Myotis lucifugus) was one of two bat species identified on Fire Island, while eight species were recorded at the William Floyd Estate.
It's interesting to note that in the mid-1970s a herd of only approximately 50 white-tailed deer (Odocoileus virginianus) was reported to be maintaining itself on Fire Island, where they have no natural predators and are protected from hunting. Within a quarter of a century, that number had swelled.
