Eastern Yellowbelly Racer
The Eastern Yellowbelly Racer, Coluber constrictor flaviventris, is a non-venomous colubrid snake. The eastern yellowbelly racer is found in the United States, from the states of Montana, North Dakota, east to Iowa and south to Texas, and southwest to Louisiana. It is also found in isolated populations in Canada, and is listed as an endangered species in the province of Saskatchewan.
It is capable of attaining lengths of 60 inches. As an adult, its color is an olive gray-green, with a yellow underside. As a juvenile it is remarkably different, having a tan or cream colored body with brown or gray blotches. Their color gradually changes as the snake ages, becoming solid olive gray-green around a year old.
Racers are diurnal, active predators. They are fast moving, and are often quick to bite if handled. They generally eat rodents, lizards, and frogs, but as juveniles they will also consume various kinds of soft bodied insect. They are fairly nervous snakes, and as such, do not typically fare well in captivity.
