Coluber constrictor flaviventris, commonly known as the eastern yellow-bellied racer, is a nonvenomous species of snake belonging to the colubrid family. This snake is found in certain regions of North America, including the eastern parts of the United States and southeastern Canada.
The eastern yellow-bellied racer is characterized by its slender and elongated body, typically measuring around 2-4 feet in length. They have a distinctive color pattern, with a dark greenish-brown or black-colored dorsum and a vibrant yellow underside. The dorsal scales are smooth, giving the snake a glossy appearance. Its head is slightly elongated and rounded, with large eyes and a thin mouth.
As the name suggests, the eastern yellow-bellied racer is a highly active and agile snake. It is known for its exceptional speed and agility, making it an adept climber and excellent swimmer. This species primarily inhabits various types of open environments like meadows, grasslands, marshes, and woodland edges. It feeds predominantly on small mammals, birds, lizards, and amphibians.
Unlike some other snakes, the eastern yellow-bellied racer does not possess venomous fangs or venom glands. As a result, it relies on constriction to subdue and kill its prey before swallowing it whole. This species is generally non-aggressive towards humans but may exhibit defensive behavior when threatened, often vibrating its tail or releasing a strong odor as a deterrent.
The conservation status of Coluber constrictor flaviventris is considered of least concern, as it is a relatively abundant and widely distributed snake species with no significant threats to its population. However, habitat loss and fragmentation due to urbanization and agriculture may pose long-term risks to their overall population and habitat range
