Coluber constrictor snakes vermont11/20/2023 ![]() ![]() Systema Naturae per Regina tri Naturae secundum Classes, Ordines, Genera, Species, cum Characteribus, Differentiis, Synonymis, Locis. Status: Locally common in some parts of the state.Įtymology: Coluber – (Latin) meaning snake constrictor – constrictus (Latin) meaning ‘drawn together’ f oxii – (New Latin) patronym for Charles Fox (1815-1854) priapus – Priapus (Latin) Roman god of male creative power. Main predators are other snakes and raptors. Eats a variety of animals, including arthropods, worms, amphibians, reptiles, birds, and small mammals. The young, 20-35 cm TL, hatch in September. Mates in May and June and female lays 10-20 eggs in late June or July. If cornered, vibrates the tail tip and can be counted on to strike repeatedly. Natural History: Alert and agile, often raises its head above the ground to look around, and reacts to disturbance by moving away quickly. Habitat: A variety of habitats including forests, open areas, and edges of forests near open fields. Hatchling and juvenile up to about 80 cm TL, blue-gray with 55-85 reddish brown blotches on back that become less distinct toward tail, and small dark spots along sides and belly. Throat distinctly lighter (yellow in northwest, white elsewhere). Phillipsĭescription: Adult long (up to 150 cm TL) and slender with shiny, uniformly blue, blue-green, or black back. But then not many species do.Juvenile North American racer, Perry County, Illinois. When cornered they may vibrate their tail in another rattlesnake imitation. 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. Racers in turn are prey for a variety of hawks as well as falcons, skunks and badgers. 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. 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. They have fairly wide, distinct heads with round snouts and large eyes with round pupils. 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. The Eastern Yellowbelly Racer ( Coluber constrictor flaviventris) is a long, lean, fast snake.
