The complete county distribution, spread across 5 Rhode Island counties. Every occurrence record falls in one county, so these sum to the total. Counties from GBIF and US Census boundaries.

Fishers have reclaimed much of southern New England and use Rhode Island’s larger wooded tracts, especially where dense cover and connected travel corridors remain. The generated record pattern names Ninigret, Trustom Pond, and Napatree Point, but their open coastal landscapes are less characteristic than nearby forest and shrub cover; treat those points as documented observations, not a habitat prescription.

Records occur throughout the year with peaks in January and March. A fisher is long-bodied, dark, and low to the ground, with a fully furred tapering tail; brief road or trail crossings are typical. Despite a persistent nickname, it is not a cat, and unverified screams at night are poor evidence of its presence.
