Blue Racer

Introduction to the Blue Racer Snake

The Blue Racer Snake (Coluber constrictor foxii) is a species of snake that inhabits open woodland and scrub areas of North America. Its range extends from eastern Texas to Manitoba, Canada and extends as far east as western New York and the Upper Peninsula of Michigan. This species of snake is the fastest in the Coluber genus and has a vivid blue coloration, giving them their common name. In addition to their color and speed they are also commonly known for their playful and curious behavior, often moving around quickly but not aggressively. The average size of a Blue Racer is around three to four feet (1-1.2 m) in length, though some larger specimens as much as seven feet (2.1 m) have been found in the wild.

Physical Characteristics

The Blue Racer has a slender build and narrow, pointed head. It is typically dark blue in color, often with black mottling on the neck and side. The ventral scales are typically paler in color, ranging from grayish-blue to lighter blue or off-white. Its eyes are amber in color and its pupils are elliptical shaped. It has smooth scales, no keels, and can be identified by its large size, pattern, and coloration.

Diet and Hunting Behavior

The Blue Racer feeds mainly on amphibians, small mammals such as rodents, and small reptiles. The snake is an opportunistic hunter and will feed on eggs, insects, spiders, and arthropods when available. Unlike other snakes, it actively hunts its prey instead of lying in wait for it to pass by. It locates its prey by sight and scent. It can move quickly and is known to strike at a surprising speed. The Blue Racer also has some characteristics of a constricting snake, although it rarely wraps around its prey to catch it.


The Blue Racer is an ovoviviparous species. Breeding takes place in the spring and summer months. Females typically lay between four and eight eggs, which have a soft, leathery shell and an edible white inner membrane. The eggs are usually laid near hollow logs and other dark, moist hiding places and can take up to two months to hatch. The hatchlings are already quite large, measuring around 7-10 inches (18-25 cm) in length. They are independent at birth and their diet consists mostly of rodents, small birds, insects and worms.

Habitat and Range

The Blue Racer is found in wooded and brushy areas. It is most commonly seen in bottomland hardwood forests, pastures and fields, open woodlands, and near creeks, swamps, and ponds. It is widely distributed across North America and is found in most states east of the Mississippi River.

Conservation Status

The Blue Racer is a fairly common species that is widely distributed across its range. It is not listed on any conservation lists, although some of its local populations are declining due to habitat loss and fragmentation. As long as its habitat is preserved, the Blue Racer should remain a common resident in its range for many years to come.


The Blue Racer is a fascinating species of snake that is one of the fastest of its kind. Its curious behavior and beautiful blue coloration give them a unique look and characteristic that they are often sought after by herpetologists and snake enthusiasts alike. Coupled with its wide distribution and resilience, the Blue Racer is sure to remain a common part of North America’s wildlife for years to come.
