Overview
The North American Racer is a widespread and highly active snake found across a large portion of the United States and neighboring regions, often seen moving quickly through fields and open habitats.
Despite its scientific name suggesting constriction, it does not actually kill prey by constriction but instead subdues small animals directly with its jaws.
How to identify it
- Coloration varies by subspecies: often solid black, blue-gray, brown, or olive as adults
- Juveniles typically patterned with blotches that fade with age
- Slender, streamlined body built for speed
- Large eyes with round pupils
- Smooth scales
- Distinguished from similar solid-colored snakes by its slender build, large eyes, and fast, alert movement

Found in a wide range of habitats including grasslands, open woodlands, farmland, and scrubland across much of the United States, southern Canada, and Mexico.
Behavior, diet & reproduction
Diurnal and highly active, often fleeing rapidly when disturbed rather than remaining still. Preys on insects, small mammals, birds, and other reptiles, swallowing prey alive rather than constricting it. Oviparous, laying eggs in summer.
