Identification and Physical Characteristics
Distinctive Coloration and Markings
The ring-necked snake is easily recognized by its unique color patterns. Its back can be olive, brown, or nearly black, while the belly is often a bright yellow, orange, or red. A key feature is the distinct neck band that can be yellow, red, or orange, which sets it apart from other snakes. Some populations may lack this band, but most individuals will have it.
Size and Scale Patterns
Adult ring-necked snakes typically measure between 10 to 15 inches (25 to 38 cm) in length. The largest recorded size is about 20.5 inches (52 cm). Their scales are smooth, and they usually have 15 to 17 scale rows at midbody.

Comparison with Similar Species
While the ring-necked snake is distinctive, it can be confused with the flat-headed snake. Here are some differences:
-
Neck Band: Ring-necked snakes have a neck band; flat-headed snakes do not.
-
Color: Ring-necked snakes are darker, while flat-headed snakes are lighter.
-
Belly Color: The belly of a flat-headed snake is pink without spots, unlike the spotted belly of the ring-necked snake.
The ring-necked snake's small size and vibrant colors make it a fascinating species to observe in the wild.
Habitat and Distribution
Geographical Range
Ring-necked snakes are found across a wide area, from southeastern Canada to central Mexico. They inhabit various regions in the United States, including:
- Eastern Seaboard from the Gulf of Saint Lawrence to Texas
- Northern Minnesota and Iowa
- Spotty populations in the Pacific Northwest
Preferred Environments
These snakes prefer habitats that offer plenty of cover and places to hide. Common environments include:
- Open woodlands near rocky hillsides
- Wet areas with abundant vegetation
- Urban areas where they can find refuge from predators
Adaptations to Different Habitats
Ring-necked snakes have adapted well to different environments. They can be found in:
- Moist habitats with rich soil
- Areas with plenty of hiding spots like logs and rocks
- Urban settings, where they can escape from threats
Ring-necked snakes thrive in various habitats, showing their ability to adapt to both natural and urban environments. Their flexibility in habitat choice helps them survive in changing landscapes.
Behavior and Lifestyle
Nocturnal and Crepuscular Activities
The black snake with a red ring around its neck is primarily nocturnal, meaning it is most active during the night. It often hunts during twilight hours, which is when it can find food while avoiding many predators. This behavior helps it thrive in various environments.
Social Structure and Colonies
These snakes are generally solitary creatures, but they can sometimes be found in small groups. They may gather in communal dens during colder months. Here are some key points about their social behavior:
-
Solitary Nature: Most of the time, they prefer to be alone.
-
Communal Dens: They share dens with others during hibernation.
-
Territorial Behavior: They can be territorial, especially males during mating season.
Defensive Mechanisms
When threatened, the black snake with a red ring has several ways to protect itself:
-
Camouflage: Its coloration helps it blend into the environment.
-
Feigning Death: It may play dead to avoid being eaten.
-
Biting: If cornered, it can bite, but it is generally non-venomous.
The black snake with a red ring is often mistaken for more dangerous species, like the coral snake. This is especially true for snakes such as coral snakes and kingsnakes, with the non-venomous kingsnake mimicking the extremely venomous coral snake. Learning to identify them can help in avoiding unnecessary fear.

The ring-necked snake primarily feeds on a variety of small creatures. Its diet includes:
-
Amphibians: such as salamanders and frogs
-
Invertebrates: including earthworms and slugs
-
Small mammals: occasionally, it may consume small rodents
Hunting and Feeding Techniques
These snakes are nocturnal hunters, using a combination of techniques to capture their prey:
-
Striking: They quickly strike at their prey.
-
Constriction: Larger prey are immobilized using a mild venom.
-
Swallowing: Smaller prey are often swallowed alive.
Role of Venom in Prey Capture
While ring-necked snakes are not highly venomous, they possess a specialized structure called the Duvernoy's gland. This gland helps them deliver venom through their rear fangs, which aids in subduing prey. The venom affects the prey's ability to escape, making it easier for the snake to consume it.
Ring-necked snakes are often mistaken for garden snakes due to their non-aggressive nature and small size. They play an important role in controlling pest populations in their habitats.
Reproduction and Life Cycle
Mating Behavior
Ring-necked snakes typically mate in the spring. In some subspecies, mating can also happen in the fall, with a process called delayed implantation. Females attract males by releasing special scents from their skin. Once a male finds a female, he moves his mouth along her body and bites her around the neck ring to align their bodies for mating.
Egg Laying and Hatching
Females lay their eggs in loose, airy soil, often under rocks or in decaying logs. The number of eggs can range from three to ten, and they are usually laid in early summer. The eggs are elongated and white, with yellow ends. They typically hatch in late summer or early fall, around August or September.
Juvenile Development
When they hatch, the young snakes are already able to take care of themselves. They do not receive any parental care and must fend for themselves right away. This independence is crucial for their survival in the wild.
Ring-necked snakes are fascinating creatures with unique reproductive habits that help them thrive in various environments.
