Big Cypress Fox Squirrel
The Big Cypress fox squirrel (Sciurus niger avicennia) is a unique subspecies of the Eastern fox squirrel (Sciurus niger) found south of the Caloosahatchee River and west of the Everglades region of Florida. Big Cypress fox squirrels (BCFS) prefer to live in the following natural habitats: pine forests, cypress swamp forests, tropical hardwood forests, oak woodlands, coastal broadleaf evergreen hammocks, and mangrove swamps.
A Big Cypress National Preserve Resource Management study revealed that BCFS consume the following food items in natural habitats: pine and cypress seed cones, bromeliad floral buds/leaf stem tissue, pond apple fruit, cabbage palm fruit, cocoplum berries, Eastern lubber grasshoppers, purple thistle flowers/seeds, saw palmetto berries, wax myrtle berries, fungi, and hog plum fruit.
Big Cypress fox squirrels prefer habitats with open canopy and low/sparse understory characteristics, and are dependent upon the availability of appropriate nest trees/nest substrate materials and year-round food resources.
The BCFS was once a game species in Florida. However, from the 1950s-1970s, populations declined noticeably throughout their range, which led the Florida Fish and Wildlife Conservation Commission (FWC) to ban BCFS hunting in 1972, and protect the BCFS as a threatened species.
Historic and present declines in BCFS populations have been attributed to habitat fragmentation and loss, habitat modification – including exclusion of fire and changes in hydrological conditions, hunting, poaching, wildlife diseases, predation, road mortality, and hurricanes.
The long-term survival of the BCFS is dependent upon the habitat management practices of private and public lands, where the use of prescribed fire, the control of invasive non-native plants/animals, and the maintenance of natural hydrologic conditions are necessary to retain habitat characteristics that benefit the BCFS.
Where Can I See a Big Cypress Fox Squirrel?
Although BCFS are rare in natural habitats, the following information will help improve the odds of seeing one. Big Cypress fox squirrels are typically found in their nests within approximately one hour of sunset and begin their daily activity approximately 1–2 hours after sunrise. Therefore, the best time to see one is typically between 9:00-4:00 pm.
The best habitats to see BCFS are pine forests and cypress swamp forests; especially if either pine seed cones or cypress seed cones are present. The best areas within Big Cypress National Preserve to see BCFS (that are accessible by street legal vehicles) include:
Please report BCFS sightings to either: e-mail us; (239) 695-1173, or any Big Cypress National Preserve employee at Headquarters and/or either visitor center.
Interested in Learning More About the Big Cypress Fox Squirrel?
From May 2007–April 2011, Big Cypress biologists and project staff used radio-telemetry to examine home range and habitat use of 10 female and 10 male BCFS in Big Cypress National Preserve. The Big Cypress fox squirrel study has yielded new information on BCFS ecology, new effective survey and trapping techniques, and represents the first successful home range and habitat use study of the BCFS in natural habitats.
The following report, "Big Cypress fox squirrel Home Range and Habitat Use in Cypress Dome Swamp and Pine Forest Mosaic Habitats," provides a summary of the core findings and techniques of the Big Cypress fox squirrel study in a format that benefits agency, interagency, and public BCFS stake-holders.

Did You Know?
The great white heron is very similar to the great white egret. However, look closely and you will see that the heron has yellow legs, while the egret has black legs. The great white heron is found only in south Florida in the United States. It can also be found on several caribbean islands.
