Blue Racer Snake

The Blue Racers are a subspecies of the Coluber constrictor or Eastern Racer Snakes. These non-venomous snakes belong to the Colubridae family. They are found in various regions of North America. Previously, there was some controversy about designating the Blue Racers as a distinct subspecies. Some people believed they should belong to the “yellow-bellied racer” subspecies. But now the Blue Racers have been accepted as a separate sub-species of the Eastern Racers.

Behavior

Find out about the behavior patterns of the Blue Racers:

  • They are diurnal in nature, being active during daytime.
  • They prefer to spend most of their time on ground.
  • A large number of Blue Racers can live in single habitat as they are not territorial in nature.
  • These snakes are very active as foragers.
  • They are known to forage both on ground and trees.
  • The Blue Racer Snakes are very intolerant of human activity. Due to this reason they prefer to live in areas with little human habitation.
  • While foraging, they hold their heads up and move very fast through underbrushes.
  • These Snakes tend to escape into small trees and bushes if threatened.
  • They can inflict a painful bite if cornered and annoyed.
  • When threatened, the Blue Racers vibrate their tails to make a buzzing sound that works as a warning for other snakes of this species.

Predators

Large birds of prey including northern harrier, red-tailed hawk and great horned owl are known to prey on this snake. Other predators include Coyotes, Raccoons, Foxes, Dogs and various wild Cats. The Blue Racer hatchlings and eggs are the prey of various carnivorous birds and mammals.

Adaptations

They have the following adaptive features to help them survive in their natural habitat.

  • These Racer snakes can move very fast. This helps them to catch prey and to avoid being preyed on.
  • They are great climbers and can easily climb on large trees to hunt or to hide from predators.
  • Their strong eyesight also helps them in hunting.

Mating Season

Their mating season starts around April and continues through May.

Reproduction

Female Blue Racer Snakes mature at 2 years of age, but they cannot reproduce until they become three years old. The males become physiologically mature at 11 months. But they are able to reproduce only after reaching 2 years of age. These oviparous snakes generally reproduce twice every year. The females build their nests in sand, tree cavities, leaf litters and unoccupied burrows of small mammals. They lay 6 to 25 eggs in communal dens during late June and leave the dens afterwards.

Life Cycle

The Blue Racer Snake eggs hatch in August or early September. These white, oval eggs are 2.5 cm to 3.9 cm long with leathery shells. Hatchlings use their “egg tooth” to cut their way out of the eggs. The hatchlings do not receive any parental care, but they may remain near the female Blue Racers for a few hours after birth.

Lifespan

Their lifespan ranges from 15 years to 20 years.

Hibernation

They are known to hibernate in groups during the cold winter months. Hibernation generally takes place in rocky mountain areas.

Blue Racer Snakes as Pets

These snakes are generally not kept as pets for their aggressive nature. They tend to attack and bite anyone who approaches them. Their large size also makes it difficult to keep them in glass tanks or cages. Due to these reasons, they do not make good pets.

Conservation Status

The Blue Racers are included in the “Endangered” category by the IUCN. They are on the Endangered Species List of Ontario since 1971 and are protected under the Endangered Species Act. Among the areas protected for these Racer Snakes, the Lighthouse Point Provincial Nature Reserve and the Stone Road Alvar Complex are most important.

  2. Wanda Major says:

    Twice in my life I’ve had a pretty pale blue,clear looking snake, no stripes, race right TOWARD me. Once was in about 1952 in the sandhills of Nebraska beside a cattle tank and the second on a sandy road in the sandhills in about 1959. Being scared I ran! My question is, would those have been blue racers and are they normally in any way aggressive like that? Neither snake could have helped but have heard and seen me.

    • Craig says:

      Contrary to what I have read, blue racers can be a bit aggressive. They use to race toward us on my grandfather’s farm in Ohio. Two of us were bitten on the heels by the little suckers.

  3. Vicki Pigg says:

    We had several here last year but I think the dog got a lot of them, this morning I saw one go under my deck near the water hose. I have told everyone to leave them alone since they help to keep rodent population in check.

  4. Aaron Johnson says:

    I was walking home from school one day and found this pretty bluish purple snake on the ground. it had a very light bluish white belly. Very pretty snake to see. It also was about 20-22inches long.

    I ran across a huge blue racer in Cadillac, MI area summer of 2013. It must of been 5feet in length. I happened upon it walking up a hill & it was sunning itself until I scared it away. It went fast and hid in the brush. WoW! what a scare and a thrill at the same time.

  7. Phyllis says:

    I live on the east side of the Cascade mountains in N. central WA and I seen a blue racer. I was walking my dogs along side of a road and the snake reared up from some rocks towards my one dog very fast and the dog reared back and didn’t want any part of that snake. That is the first time I have ever seen a blue racer, I can tell you he was not friendly he scared me and the dog. I was curious so I looked the snake up and did find that they live in this part of WA. This happened in 2011.

  8. margareta says:

    Last year i found about 30 blue runners in tangle of netting on my property in butte la rose louisiana. After the first fright i tried to separate them. Some were able to escape but most of them died. I do not understand their attraction to the net, it was a net used to cover fig trees to protect from birds. I live in abita springs louisiana and i see lots of them. They are beautiful and fast.

  9. Charles Kleinpeter says:

    My wife and I live in Hancock County, Miss. Which has flat to hilly terrain. The Runners used to come and sun on our front deck in early Spring. I saw a lot of them and if they sensed no harm and I walked slow they would travel along with me. I saw one this AM about 5-6 feet long. They are never harmed because of their rodent farming.

    I saw a blue racer here in my yard in south Carolina . I had never seen a blue snake before so we looked it up.IT WAS JUST A BABY. HOPE I DONT EVER MEET MAMMA

  13. Howards says:

    We have had blue racers living around some broken concrete around our in ground pool. They help keep the mice and frog population down and we have enjoyed watching them. We just had some excavation done to fix the concrete and are worried they may not stick around because their den has been disrupted. Does anyone have any idea how we can encourage them to stay?
