#Coluber constrictor foxii snakes of michigan Patch#
Killed moving from one patch of habitat to another. Where populations exist, this species is extremely vulnerable to being Habitat is often fragmented due to development and roads and in areas This has gotten to the point that usually the only turtle nests one canįind is a predated nest by racoons. Raccoon has learned is raiding turtle nests which have been freshly laid. Species ability to adapt the modern urban landscape and capitalize onīeing an opportunist when it comes to feeding. This explosion in population is due to the RaccoonsĪre estimated to occupy 700-800% of their original population numbers at Threats to the longterm survival of this species in Michigan. Even today, nest predation and road mortality are the most significant Any sightings of this species should be reported to the Michigan Herp Atlas.Ī Species of Special Concern in Michigan, this species has declinedĭrastically from its former distribution in the state. This problem and the decline of this species has led to it being listed as a Species of Special Concern. If there is no recuitment of juveniles, then once the old adults die off, we will have little or no members of this species left. Blandings may take 14-15 years to reach sexual maturity and the fact they we don't see many young Blanding's turtles is alarming. Though adult Blanding's turtles seem to be fairly common throughout Michigan, we must understand that most of these turtles are likely 20-25 years of age at minimum. Turtles are long-lived, and species like the Blanding's turtle may live for 80 years or more. This had lead to a dangerous shift in turtle populations. Raccoons and other mammals like the red fox have becomes efficient predators of turtle eggs and are able to follow scent trails left by nesting female turtles to nest sites, where they predate entire turtle nests within 24-48 hours of being laid. Not only are these roadways for human traffic, but also for causeways for wildlife species including raccoons. Many people often fail to pay attention and run nesting turtles down by accident, and unfortunately sometimes intentionally. If you encounter a skink in the field, be careful not to handle it by or near the tail to ensure that the skink has this line of defense for when it is actually needed. Some females retain some of the blue coloration seen in juveniles as shown in the photo above.
The tail regrows over time but cannot be dropped again during the skink's lifetime. The tail breaks cleanly and will often writhe and wriggle for a minute or two by design to distract the predator so that the skink can escape. Juveniles skinks are dark black with bright cream stripes and a brilliant blue tail, which can be dropped in the event of an attack by a predator. During this time, the head of the male swells and becomes a brilliant orange-red and the body becomes a tan or gray coloration. These lines may become obscured or absent in males during the breeding season. It is easily characterized by the five light colored lines running from the snout down the back and into the tail. The five-lined skink is the more common of Michigan's two species of lizard. If you encounter a massasauga in the field, admire it from a distance and let it be. There are usually a couple of bites which occur every few years in Michigan, and almost all of them haveoccured when a person was trying to pick up or kill the snake.
It is only when they are cornered or harassed that they become defensive, coiling and sounding their rattle which is a high-pitched buzz that is very quite audible. When approached, most massasaugas will remain motionless and rely on their camouflage while others may try to escape. They are also shy, and would rather avoid confrontations with humans. Massasaugas are extremely secretive, and spend much of their time coiled among tall sedges and grasses in the wetlands they inhabit. Juveniles wiggle to attract unsuspecting prey items.
The end of the tail is bright yellow which Juveniles are a light gray and have only a small button at This allows the massasauga to detect ambient heat and makes it able to It has vertical, cat-like pupilsĪnd a heat sensing pit which is located between the eye and the nostril. Massasaugas have a wide, arrow-shaped head which is very distinct from
