North Carolina, with its diverse ecosystems ranging from mountains to coastal plains, is home to several species of black snakes. While the name "black snake" is often used generically, it's crucial to understand the specific species you might encounter to ensure safe and responsible interaction. This guide will explore the common black snakes found in North Carolina, their identifying features, behaviors, and how to coexist peacefully.
What Kinds of Black Snakes Live in North Carolina?
Several snake species in North Carolina are predominantly black or dark-colored, leading to the common term "black snake." The most frequently encountered include:
-
Black Rat Snake (Pantherophis obsoletus): This is likely the snake most people envision when they hear "black snake." They are large, non-venomous constrictors, often reaching lengths of 4-6 feet. While predominantly black, juveniles can exhibit patterns. Their smooth scales and relatively slender build distinguish them from other similar species.
-
Eastern Black Racer (Coluber constrictor priapus): These snakes are sleek and fast, often exhibiting a jet-black coloration although some may have a faint grey or brown hue. They are also non-venomous and known for their speed and agility. They're easily identified by their pointed head and keeled scales (scales with a raised ridge).
-
Eastern Hog-nosed Snake (Heterodon platirhinos): While not always entirely black, they can range in color from brown to black and are often mistaken for other black snakes. They are known for their upturned snout and their remarkable defensive behavior of playing dead, including gaping mouths and even emitting a foul-smelling musk.
How Can I Identify a Black Snake in North Carolina?
Identifying a snake to the species level can be challenging, even for experienced herpetologists. Key features to look for include:
- Size and Body Shape: Note the snake's overall length and the thickness of its body. Black rat snakes are relatively thick-bodied, while black racers are more slender.
- Head Shape: The head shape can provide clues. Rat snakes have a slightly wider head that's not sharply distinct from the neck, while racers have a more pointed head. Hog-nosed snakes have a distinctly upturned snout.
- Scale Texture: Feel the snake's scales (if you can do so safely from a distance). Racers have keeled scales, while rat snakes have smooth scales.
- Coloration and Patterns: While many are primarily black, juveniles might display patterns that fade with age. Look for any subtle variations in color or the presence of markings.
- Location: The snake's habitat can provide helpful information. Rat snakes are more often found in wooded areas and near water sources, while racers prefer open fields and sunny locations.
Are Black Snakes Venomous in North Carolina?
No, the common black snakes found in North Carolina – black rat snakes, eastern black racers, and eastern hog-nosed snakes – are not venomous. They are constrictors, meaning they subdue their prey by wrapping around it and squeezing until it suffocates.
What Do Black Snakes Eat?
The diet of black snakes in North Carolina varies depending on the species:
- Black Rat Snakes: Primarily feed on rodents, birds, and their eggs.
- Eastern Black Racers: Eat lizards, snakes (including other racers!), frogs, and rodents.
- Eastern Hog-nosed Snakes: Consume toads, frogs, and other amphibians.
What Should I Do If I See a Black Snake?
Most black snakes are harmless and beneficial to have around as they control rodent populations. The best course of action is to admire them from a safe distance and leave them undisturbed. Avoid approaching, handling, or attempting to kill them. If the snake is in an area where it poses a direct threat (e.g., near children or pets), carefully contact a local wildlife removal expert or your local animal control agency.
How Can I Prevent Black Snakes from Entering My Home?
Keeping your yard and home clean and tidy is crucial. This includes:
- Removing potential food sources like rodents and other small animals.
- Sealing any cracks or gaps in your home's foundation or exterior walls.
- Keeping grass trimmed and brush cut back from the house.
- Storing firewood away from the house.
By understanding the different species of black snakes in North Carolina and their behaviors, you can learn to coexist peacefully and appreciate the role they play in the local ecosystem. Remember, responsible observation and respecting their natural habitat are key to ensuring a safe and harmonious relationship with these fascinating reptiles.
