At the mid belly, black or brown invades the white, and posteriorly, the ventrals are a shiny bluish black. Western rat snakes breed in late May and early June.

The upper lip, chin, and lower part of the neck are usually white. At the northern limits of their range, distribution appears to be restricted by the availability of suitable hibernating sites.

Darkening occurs rapidly as they grow. The skin between the scales along the sides may be red.

[1] The eastern massasauga has been listed as a candidate species on the United States Endangered Species Act since 1999. Rat snakes breed in the spring and the female deposits about 15 eggs in rotting wood in late summer. Although it can defend itself by trying to bite, by vibrating its tail ominously, and by smearing a stinky musk on attackers, this snake often becomes food for hawks and other predators.

[14] As of 2016, the massasauga is listed as Threatened under the Endangered Species Act.[15]. This pattern fades quickly, and the young snake will reach adult coloration in about two or three years.

Pantherophis obsoletus – also known as the western rat snake, black rat snake, pilot black snake, or simply black snake – is a nonvenomous species of Colubridae found in central North America. The eastern rat snake is primarily active at night during the summer, and diurnal in the spring and fall. They occur in North America, Europe, and Asia east to the Philippines. The species has been found at elevations of more than 5,000 feet (1,500 m).

[23] Recent studies indicate that Ontario hospitals in rattlesnake country often do not have antivenom, as massasauga-specific antivenom is not easy to acquire.

Rat snakes live in a variety of habitats ranging from a rocky hillside to flat farmland.

These snakes probably prey on birds and birds’ eggs most heavily of all Iowa snakes because of their climbing ability and time spent in trees.

Please report any sightings of this snake in southern Iowa to us or the DNR. In these climates, the snakes require southern exposures to receive maximal thermal benefit from the winter sun and to provide basking areas in early spring and late fall.[11][13]. S. c. catenatus is rather shy and avoids humans when it can.

[4][16] It is found only near the eastern shore of Georgian Bay, the Bruce Peninsula, the North Shore of Lake Huron,[17] Wainfleet Bog, and Ojibway Prairie. They may be found on the north and east sides of bluffs; while other snake species prefer the warmer side of the bluff.

Another report describes a specimen that had eaten eight birds, most likely goldfinches, that had been attracted to a small fountain installed as a bird bath at a desert camp. [16][18][19], Pantherophis alleghaniensis has sometimes been considered a subspecies of Pantherophis obsoletus, to which it is closely related. Common. Western rat snakes are among the largest of Iowa’s snakes. Statewide. They’re a constrictor snake (which means they squeeze their prey) with a diet that consists mostly of rodents.

Adults range from 40 – 74 inches in length.

Harmless to humans. Western rat snakes are found west of the Mississippi River, from eastern and southern Iowa southward through Missouri and Arkansas to western Louisiana, westward to eastern Texas, northward through Oklahoma and eastern Kansas to southeastern Nebraska. Young are light gray or tan, with distinct dark brown or black blotches on the back and sides; a black band passes between the eyes and angles down toward the mouth.

Only two incidents of people dying from massasauga rattlesnake bites in Ontario have been recorded; in both cases, the victims did not receive proper treatment. No type locality was included in Cope's original 1867 description. Most adults have shiny, unmarked black heads and necks with bright white labial scales. In spring, early summer, and autumn, they hunt in the daytime; in hot weather, they are nocturnal. The snakes start to breed in May and June, earlier in the South. After 45 minutes and a 1 1⁄4 miles (2.0 km) walk, a tourniquet was applied and an incision made. The black rat snake is an excellent climber and uses small angles protruding from the belly scales to grip the rough bark of a tree. Reptiles, including turtles, lizards, and snakes, are also vertebrates, and most are ectothermal, but unlike amphibians, reptiles have dry skin with scales, the ones with legs have claws, and they do not have to live part of their lives in water. and Wilson, R.J. (2001).

They eat scorpions, centipedes, and spiders. [11], Adults are shiny black dorsally, with a cream or white chin and throat. Recent research has led scientists to reclassify this species in relation to its relatives, so its name has changed accordingly.
