They are quick to bite if handled and sometimes will release a foul smelling musk from their cloaca. The 8 to 10” long young hatch around late August or in the early fall. Around a month later the female will lay from 4 to 25 rather granular feeling eggs in a hidden nest site such as an abandoned rodent burrow, hollow log, beneath rocks on even and loose soil. Racers usually mate between April and June. Racers emerge from their winter hibernation when temperatures have risen sufficiently for them to be active. They regularly return to the same den year after year. Their range includes eastern Montana and Wyoming extending into the Dakotas and then south onto the central plains and down into central Texas.ĭuring the winter months they hibernate and often share hibernacula with other species such as garter snakes, milk snakes, bull snakes and rattlesnakes. In grasslands they will often move with their heads above the grass to better observe their surroundings. The habitats they utilize include grasslands, agricultural areas, marshes, sagebrush thickets, prairie, open woods and semi-arid areas. They often use their speed to flee from potential predators. The Black Racer can be found primarily in Ohios eastern and southern counties and is. Racers in turn are prey for a variety of hawks as well as falcons, skunks and badgers. The Black Racers scientific name is Coluber constrictor constrictor. The young in particular consume lots of soft bodied insects. They are not constrictors, but they may use a loop or two of their coils to pin their prey to the ground as they position their mouth in order to swallow the prey whole. The Eastern Yellow-bellied Racer is a subspecies of the North American Racer (Coluber constrictor). Their prey consists of rodents, insects, frogs, toads, lizards, snakes, reptile eggs, birds and birds’ eggs. Racers are fast moving, diurnal snakes that actively hunt. They can live for over 10 years in the wild. They can reach 5 feet long but more commonly are 3 ½ feet long. Their tails are whip like, the anal plate is divided and the scales are smooth and arranged in 17 rows. Young racers have a gray body covered with brown or red. They have fairly wide, distinct heads with round snouts and large eyes with round pupils. Racers in Michigan are a dark-blue color and have white chins. They go through an ontogenetic color and pattern change as they reach sexual maturity in one to two years.
This is an advantage unless they run into human predators who like to kill all rattlesnakes. This pattern distinctly imitates the rattlesnake. They have a tan or cream colored body with brown, grey or reddish blotches along with small brown or reddish spots below the blotches. The juveniles however are remarkably different. The other ten subspecies may be black, brown, blue or green with a lighter color belly. The adults are usually olive grey-green with a yellow belly. Besides actions such as restoring wetlands or planting resilient tree species in northern communities, research, surveys and monitoring are also among conservation actions described in the WWAP because lack of information can threaten our ability to successfully preserve and care for natural resources.The Eastern Yellowbelly Racer ( Coluber constrictor flaviventris) is a long, lean, fast snake. Further, a low ecological priority score does not imply that management or preservation should not occur on a site if there are important reasons for doing so locally.īack to Top Issues/threats and conservation actionsĬonservation actions respond to issues or threats, which adversely affect species of greatest conservation need (SGCN) or their habitats. This score does not consider socio-economical factors that may dictate protection and/or management priorities differently than those determined solely by ecological analysis. * Ecological priority score is a relative measure that is not meant for comparison between species.
