Eastern Racer snakes are frequently encountered across various landscapes, often leading to questions about their potential danger. A common misconception surrounds whether these snakes are poisonous or venomous. Eastern Racers are neither poisonous nor venomous, meaning they do not produce toxins for defense or prey capture, nor do they deliver venom through a bite.
Understanding Eastern Racers
Eastern Racers (Coluber constrictor) are a non-venomous species widespread across North and Central America, from southern Canada down to Guatemala. They possess a slender body, typically ranging from 20 to 60 inches in total length, though some individuals can reach up to 75 inches. Adult coloration varies significantly by subspecies, appearing as solid black, gray, blue, green, brown, or olive, usually with a lighter underside that can be white, cream, or yellow. Juveniles, however, display a distinct pattern of dark blotches on a lighter background, which fades as they mature.
These adaptable snakes inhabit a wide range of environments, including open grasslands, meadows, forest edges, suburban areas, and roadsides. They are often seen in places with ample cover like brush and shrubs. Their large eyes facilitate keen eyesight, allowing them to survey their surroundings effectively.
Their Natural Behavior
Eastern Racers are named for their remarkable speed, capable of moving at speeds up to 3.5 to 4 miles per hour when attempting to escape. They are diurnal, meaning they are active during the day, foraging for food. Their diet is diverse, including insects, small rodents, frogs, lizards, other snakes, and even bird eggs and young birds. Instead of constricting their prey, as their scientific name Coluber constrictor might suggest, they typically overpower it by pinning it down or simply swallowing smaller items whole.
While Eastern Racers are not aggressive, they will defend themselves if they feel cornered or threatened. When agitated, they may vibrate their tail against dry leaves, creating a rattling sound to deter potential threats. If provoked, they might bite, but these defensive bites are generally superficial.
Encountering an Eastern Racer
If you encounter an Eastern Racer, the most appropriate action is to maintain a safe distance and observe it without disturbing its natural movements. These snakes are typically shy and will usually flee quickly when approached. Allowing the snake space gives it the opportunity to move away, which is their preferred response to perceived danger. This approach minimizes any potential for a defensive interaction.
In the uncommon event of a defensive bite from an Eastern Racer, the wound should be cleaned thoroughly with soap and water. Applying an antiseptic to the area can help prevent infection. However, observing basic wound care practices can help ensure proper healing.
