The Fox Snake Is Essential for the Great Lakes Region

Fox snakes have very distinctive coloration and markings, which help them blend into their surroundings.

Eastern fox snakes have a base color of light brown to yellowish, with large, dark brown or black blotches running down their backs. These blotches give them a striking appearance and makes them easy to confuse with rattlesnakes, although fox snakes are harmless.

Their bellies are usually a yellow or cream color, marked with a checkerboard pattern of black.

Adults can grow quite large, typically ranging from 3 to 5 feet (0.9 to 1.5 meters) long, though some can reach up to 6 feet (1.8 meters). Young snakes are smaller, but they sport similar markings. Their slender bodies and smooth scales make them excellent climbers and swimmers.

Western fox snakes have slightly different coloration — more of a reddish-brown hue — but they share similar black blotches along their back.

Fox snakes are divided into two main subspecies: the eastern fox snake and the western fox snake. Eastern fox snakes are more commonly found in the Great Lakes region, especially around Michigan, Ohio and Ontario. They prefer wetland habitats and are often seen near Lake Erie.

The western fox snake, on the other hand, inhabits areas further west, such as parts of Wisconsin, Minnesota and the Dakotas.

Despite differences in coloration, both subspecies are excellent at blending into their surroundings, thanks to their patterned bodies and preference for burrowing into mammal burrows or natural crevices.

Fox snakes are solitary animals, which means they spend most of their time alone, except during the mating season. They’re diurnal, meaning they’re active during the day, especially in the early morning or late afternoon.

In colder regions, fox snakes hibernate during the winter, often finding refuge in mammal burrows or rock crevices to stay safe from freezing temperatures.

When threatened, fox snakes can be quite the actors! They’re harmless snakes, but they’ll vibrate their tails in dry leaves, mimicking a rattlesnake to scare off predators. This behavior often leads to mistaken identity, as people think they’ve encountered a venomous snake, even though fox snakes pose no danger to humans.

They may also emit a musky odor when they feel threatened, adding to the illusion of being more dangerous than they really are.

Fox snakes are excellent hunters, and their diet primarily consists of small mammals like mice, rats and voles. They are constrictors, meaning they wrap around their prey and squeeze tightly until the animal can no longer breathe, before swallowing it whole. This ability makes them an important part of controlling rodent populations in their environment.

In addition to small mammals, fox snakes occasionally eat birds and bird eggs. They are strong climbers and will sometimes raid bird nests if the opportunity presents itself.

Young snakes often feed on smaller prey like frogs or insects until they’re large enough to handle bigger meals. Their varied diet helps them survive in different habitats, but they are especially fond of hunting in grassy fields and wetland areas.

Fox snakes are most commonly found in the Great Lakes region, where they thrive in a range of habitats, from wetlands to forests and even farmland. They are particularly fond of wetland habitats, where the abundance of small mammals makes for easy hunting. These snakes are often seen near water, like marshes, rivers and the shores of Lake Erie, where they can also find places to hide.

Despite their adaptability, fox snakes are sensitive to habitat loss. Wetland destruction and urban development have significantly reduced the amount of suitable land for fox snakes to live and hunt. Their reliance on wetland areas and mammal burrows means that any disruption to these environments can negatively impact fox snake populations.

The life cycle of a fox snake begins when females lay eggs in the summer. Female fox snakes lay their eggs in hidden, warm areas such as rotting logs, decaying vegetation, or mammal burrows, where the temperature and moisture levels are just right.

A typical clutch consists of seven to 29 eggs, and after about two months, young snakes emerge, fully formed and ready to fend for themselves.

Young snakes are born independent, and their early lives are spent hiding from predators and searching for small prey. It takes about two to three years for them to reach maturity. Once they’ve reached adulthood, fox snakes can live up to 12 years in the wild, though their lifespan can be shortened by habitat destruction or encounters with humans.

The eastern fox snake is currently considered a threatened species in some regions, particularly around the Great Lakes. Wetland destruction, urban development and persecution by humans have contributed to the decline in their numbers. Many people mistake these harmless snakes for dangerous species and kill them out of fear, further threatening the already vulnerable population.

Conservation efforts are in place to protect fox snakes and their habitats, particularly in Michigan and Ontario. Wetland restoration projects and public education programs are helping to raise awareness about the importance of these snakes in controlling rodent populations and maintaining ecological balance.

Protecting fox snakes means protecting wetland habitats, which are crucial for many species in the Great Lakes region.
