The Blue Racer Snake (Coluber constrictor foxii) is a non-venomous snake native to North America. As one of the largest members of the Colubridae family, the Blue Racer Snake can grow up to six feet in length and is easily identified by its sleek, slender body and distinct blue-grey coloration. In this blog, we will explore the characteristics, habitat, behavior, diet, and conservation of this fascinating species.


The Blue Racer Snake has a slender, cylindrical body with smooth scales that give it a glossy appearance. They have large, round eyes with vertically elliptical pupils that allow them to see in low-light conditions. Their blue-grey coloration on the dorsal side of their body fades to white on their underside.

Younger snakes are typically more vividly colored, with darker blues and greys, while older snakes may appear more brown or green. Their scales are arranged in a pattern that creates a distinct “checkerboard” appearance on their back.


The Blue Racer Snake can be found in a variety of habitats throughout North America, including prairies, open woodlands, and grasslands. They prefer areas with plenty of sun exposure and are often found basking on rocks or other surfaces. Blue Racers are also known to inhabit areas near water sources such as streams or ponds.


Blue Racer Snakes are active during the day and are known for their speed and agility. They are excellent climbers and swimmers and are not afraid to enter the water to hunt for prey or escape predators. Blue Racers are also known for their aggressive behavior, and will often strike if they feel threatened or cornered. However, they are not venomous and pose little threat to humans.


The Blue Racer Snake is a carnivore, feeding primarily on small mammals such as mice, voles, and shrews. They are also known to eat birds and their eggs, reptiles such as lizards and smaller snakes, and occasionally insects. Blue Racers are skilled hunters and use their speed and agility to capture their prey.


Blue Racer Snakes face threats to their habitat from human development, habitat destruction, and fragmentation. They are also sometimes targeted by humans who mistake them for venomous snakes or view them as a threat to livestock or pets. Due to these threats, Blue Racers are classified as a species of special concern in many states and are protected by state and federal laws.

In conclusion, the Blue Racer Snake is a fascinating species with unique physical characteristics, behavior, and habitat preferences. Their beautiful blue-grey coloration and speed make them a joy to observe in their natural habitat, and their importance in controlling rodent populations and serving as prey for other animals cannot be overstated. However, it is important that we take steps to protect this species and their habitat to ensure that they continue to thrive in North America for generations to come.
