Michigan's Elusive Blue Racer Snake: A Complete Field Guide

The blue racer snake ( Coluber constrictor foxii ) is a fascinating and often misunderstood reptile native to Michigan. Known for its speed and distinctive coloration, the blue racer plays an important role in the state's ecosystem. This guide provides comprehensive information about the blue racer snake in Michigan, covering its identification, habitat, behavior, and conservation status.

Identification of the Blue Racer Snake

Accurate identification is crucial for distinguishing the blue racer from other snake species in Michigan. Here are key characteristics to look for:

• Coloration: As the name suggests, adult blue racers typically exhibit a bluish-gray or light blue dorsal (back) coloration. The belly is usually white or pale yellow.
• Size: Adults can range in length from 3 to 6 feet, making them one of the larger snake species in Michigan.
• Scales: The scales are smooth, giving the snake a sleek appearance.
• Head: The head is relatively small and slightly distinct from the neck. Juvenile blue racers have blotched patterns that fade as they mature.

Habitat and Distribution in Michigan

Understanding the blue racer's preferred habitat helps in locating and observing these snakes.

• Preferred Habitats: Blue racers favor open habitats such as grasslands, prairies, savannas, and edges of forests. They can also be found in agricultural areas and along roadsides.
• Michigan Distribution: The blue racer's distribution in Michigan is primarily concentrated in the southern portion of the state, especially in the southwestern counties. Scattered populations may occur elsewhere.
• Specific Habitat Features: Look for areas with ample sunlight, loose soil for burrowing, and a variety of prey items. They often utilize logs, rocks, and other debris for cover.

Behavior and Ecology

The blue racer's behavior is characterized by its speed and agility. Here are some notable aspects of their behavior and ecology:

• Diet: Blue racers are opportunistic hunters with a varied diet. Their prey includes:
  • Insects
  • Rodents
  • Birds
  • Other snakes
  • Frogs
• Hunting Strategies: They are active foragers, often hunting during the day. They rely on their speed and vision to capture prey.
• Temperament: Blue racers are generally non-aggressive towards humans, but they can be defensive if threatened. When cornered, they may vibrate their tail and strike defensively. It is best to observe them from a safe distance.
• Reproduction: Blue racers are oviparous, meaning they lay eggs.
  • Females typically lay their eggs in late spring or early summer.
  • Clutch sizes can vary from 5 to 30 eggs.
  • Eggs are usually laid in decaying vegetation, under rocks, or in other protected areas.
  • The eggs hatch after an incubation period of about 2 months.
• Activity Patterns: Blue racers are primarily diurnal (active during the day), especially during warmer months. They become less active during colder periods and may hibernate in communal dens with other snake species.

Conservation Status and Threats

The blue racer snake faces several threats that impact its populations in Michigan.

• Habitat Loss: Conversion of grasslands and prairies to agricultural land and urban development reduces available habitat.
• Road Mortality: Blue racers are often killed by vehicles when crossing roads.
• Persecution: Misconceptions about snakes can lead to intentional killing of blue racers.
• Conservation Efforts: Protecting and restoring grassland and prairie habitats is crucial for the blue racer's survival. Public education and outreach programs can help reduce negative perceptions and promote conservation efforts.
• Listing Status: While not currently listed as endangered or threatened at the federal level, the blue racer is considered a species of concern in some regions due to declining populations. Monitoring and research efforts are important for assessing the long-term status of the species.

Distinguishing Blue Racers from Other Snakes in Michigan

Several other snakes in Michigan can be confused with the blue racer. Knowing the key differences is important for accurate identification.
