“The southern black racer spends the winter in dens with many other types of snakes.”

The southern black racer lives in the United States and Mexico. This snake is not venomous but uses its great speed to escape predators and other threats. Though it’s known as a constrictor, it doesn’t kill its prey like other constrictor snakes like boa constrictors. They are carnivores eating rodents, birds, bird eggs, and lizards. This snake has a habit of lifting its head and long neck several inches off the ground to scout out its surroundings.

Southern black racers live in a prairie habitat as well as in scrubs, pinelands, sandy areas and even venture into the backyards of homes in the suburbs.

Specifically, these snakes live underground, beneath piles of leaf litter or in thickets. They are usually found near water. These reptiles are expert swimmers.

The cold weather months are spent in brumation. In the month of October, the snakes go underground into dens containing other species of snakes. The entrance to this type of den may be located on a hillside or between two rocks in a pineland. They emerge in March and are especially active during the spring breeding season.

They are known for the bluish-gray scales. At four to six feet in size, they are about the same length as southern black racers.

Southern Black Racer: How Dangerous Are They?

Southern black racers are not venomous snakes. They are shy and use their great speed to escape humans, animal predators or any other threat. But, like most snakes, if a southern black racer is cornered or feels it has no escape from a situation, it is able to inflict a painful bite.

If a person gets a bite from a North American racer, then it’s important to wash the injured area with soap and warm water. Cleaning the area cuts down on the chance it will become infected. This snake’s bite is known to be painful so putting an ice pack on the injured area can relieve the pain. If the area doesn’t begin to heal in a few days or it becomes red or develops a rash, it’s a good move to visit a doctor about it.

Southern Black Racer Behavior and Humans

Southern black racers are active in the daytime. They are out hunting for mice, birds, lizards, and bird eggs. They are very plentiful in certain states including Florida and Louisiana. These reptiles are useful in keeping rodent populations from becoming unmanageable. So, if this snake is seen on a farm or another piece of property, it should not be considered a pest.

It’s not unusual to see this snake moving around in a suburban, wooded backyard or crossing a street bordered by fields or woods. If they are spotted by a human, they try to get away as quickly as possible. Unfortunately, these snakes are often run over and killed by cars and trucks. They are fast but not always able to get out of the way of passing traffic.
