While these snakes are harmless to humans, they are known for being quite active hunters that feed primarily on small rodents such as mice and voles.

Due to their adaptability and robust populations, it is not uncommon for Eastern racers to come into contact with humans both urban and rural settings alike. Understanding how this species interacts with people will provide key insights about how our actions affect wildlife throughout ecosystems across North America.

Eastern racer


The eastern racer, a species of non-venomous snake found in Eastern North America, is an interesting creature with many distinct characteristics. Its scientific name is Coluber constrictor and it’s also known as the black racer or blue racer.

This type of snake has several distinguishing features and can be easily identified by its long slender body, smooth scales, and grayish to dark brown coloration. The average size for this species ranges from about two feet to five feet in length.

The life cycle of the eastern racer includes mating season which takes place between April and July depending on location. Females lay eggs during late summer months then incubate them until hatching occurs approximately one month later. Predators of the eastern racer include hawks, owls, raccoons, opossums, skunks, foxes and other snakes such as rattlesnakes. They are also preyed upon by humans who hunt them for their skin or use them as fishing bait.

Eastern racers have excellent vision and speed that helps them avoid predators when they’re not camouflaged hiding among vegetation on the ground or under rocks or logs. Their diet consists mainly of small animals including rodents, frogs and lizards but they will also feed on birds‘ eggs if given the opportunity. In addition to having great eyesight and being agile hunters, these snakes have strong jaws equipped with sharp teeth used to capture prey before subduing it with powerful coils of their bodies.

Eastern racers are fairly common throughout much of their range where they inhabit fields, woodlands and marshes amongst other habitats near water sources like ponds or streams. Although they may appear intimidating due to their size and speed, these harmless creatures play an important role in maintaining healthy ecosystems by controlling rodent populations which would otherwise cause serious damage to crops or spread diseases through contact with humans or livestock if left unchecked.

Scientific Name

The eastern racer snake, also known as Coluber constrictor flaviventris, is an important species of reptile. It has a long and slender body that is easily distinguishable from other snakes in its range. Its scientific name comes from the Latin terms “coluber,” meaning “snake”, and “constrictor” which refers to its ability to coil around prey and squeeze it with powerful muscles. This particular species of snake inhabits wooded areas such as forests, meadows, and wetlands throughout much of North America.

Eastern racers have been studied extensively by scientists since the early 19th century. They are highly adaptive creatures that can quickly adapt to changes in their environment. As a result, they inhabit both urbanized and rural areas alike. Studies conducted on these animals indicate that population sizes vary greatly depending upon local conditions such as predation rates and availability of food sources.

Racer snakes have an interesting scientific history due to their wide array of common names; some experts refer to them as “black rat-snakes” or simply “racers” while others call them rattlesnakes or rattleless vipers based on their external appearance alone.

In addition to this variety of colloquialisms, biologists often use the term Coluber constrictor flaviventris when referring to this species specifically. Ultimately, regardless of what one calls it – whether scientifically or casually – the eastern racer remains an essential part of many ecosystems across the continent today.

Geographic Range

The eastern racer, Coluber constrictor, is found throughout much of the Eastern United States and Canada. Its geographic range extends from as far south as Florida to as far north as Ontario. The following are key points regarding the distribution of this species:

  1. Eastern Racer Range: This nonvenomous snake’s range includes most states east of the Rocky Mountains, excluding New England and some parts of upper Midwest (Minnesota). It also occurs in southern Canada in provinces such as Quebec and Ontario.
  2. Habitat: Inhabiting open forests, grasslands, scrubland, marshes and wetlands, eastern racers prefer sunny locations with plenty of ground cover for hiding or basking in the sun.
  3. Migration: This species migrates seasonally between its hibernation sites during winter months and summer activity areas used for mating and feeding.
  4. Locations: This diurnal serpent can be seen around residential properties where it enjoys hunting small rodents like mice, voles and chipmunks.
    In addition to these characteristics of its geographical range, eastern racers may travel long distances when seeking new habitats or mates; however they typically remain within their home ranges year-round unless food sources become scarce or temperatures drop too low for survival. As a result of its wide yet restricted range across North America, Coluber constrictor has been designated an endangered species in several states including Pennsylvania and West Virginia due to habitat loss or degradation caused by human development.

Habitat And Diet

Eastern racers are found in a wide range of habitats, including forests, meadows, grassland and even urban areas. They are diurnal snakes who spend most of their day seeking out prey.

ForestsInsects & other arthropods
MeadowsSmall reptiles & amphibians
GrasslandsRodents such as mice & voles
Urban AreasCarrion or dead animals

The eastern racer’s diet consists mainly of small rodents such as mice and voles. Additionally, they will feed on insects and other arthropods, small reptiles and amphibians, carrion or dead animals when available. Eastern racers generally ambush their prey by striking suddenly with lightning speed before constricting it until it suffocates. This behavior is known as strike-and-hold predation.

Eastern racers tend to be solitary creatures except during the breeding season when multiple males may pursue a single female for mating rights. During this time they can become quite aggressive towards one another resulting in serious bites that may require medical attention if left untreated. The eastern racer plays an important role in controlling rodent populations while also providing food sources for larger predators like hawks and owls.

The adaptable nature of the eastern racer makes them well suited to thrive in many different environments throughout North America. As part of the Colubridae family, these fascinating serpents play an integral role in maintaining healthy ecosystems across the continent.
