Black Rat Snake
Black Rat Snake, also known as the pilot black snake or simply rat snake, is a species of nonvenomous snake found in North America. They are typically found in wooded or rocky areas, and are known for their ability to climb trees. They are also common around farms and outbuildings, as they feed on rodents such as rats and mice. They can grow to be quite large, with some individuals reaching over 6 feet in length. They are generally not considered a threat to humans, but may bite if threatened or handled roughly.

Scientific Name and Classification
The scientific name of the black rat snakes is Pantherophis obsoletus, and it belongs to the genus Pantherophis in the family Colubridae. The Colubridae family is the largest snake family, with over 700 species. The genus Pantherophis includes several species of rat snakes found in North America, including the black rat snakes, gray rat snake, and yellow rat snake.
The species name “obsoletus” means “outdated” or “obsolete,” which refers to the fact that it was originally classified in the genus Elaphe, but later reclassified to the genus Pantherophis.
In taxonomy, the classification of black rat snake is:
Kingdom: Animalia
Phylum: Chordata
Class: Reptilia
Order: Squamata
Suborder: Serpentes
Family: Colubridae
Genus: Pantherophis
Species: P. obsoletus
Appearance
The black rat snakes has a glossy black coloration that gives it its name. Adult black rat snakes typically have a uniform black coloration, although some individuals may have some white or yellow flecks on their scales. Juvenile black rat snakes are typically brown or gray in color, with dark brown or black blotches on their back. As they mature, they will eventually turn black.
Black rat snakes have a long, slender body with smooth scales. They have a pointed head and a long, thin tail. Their eyes are large and round with vertical pupils, which are characteristic of most snakes. They have a forked tongue, which they use to detect scents. They can grow to be quite large, with some individuals reaching over 6 feet in length.
In general, black rat snakes have a sleek, glossy appearance that makes them quite striking. They are a medium-sized snake, and their body is usually thicker than their head. They have a distinctively long tail, which makes up more than half of their total body length.
Behavior
Black rat snakes are generally docile and non-aggressive. They are primarily active during the day, and spend most of their time searching for food and basking in the sun. They are good climbers and can often be found in trees and on buildings, as well as on the ground. They are also known to be good swimmers, and are often found near water sources.
Black rat snakes are opportunistic feeders, and will eat a wide variety of prey, including rodents, birds, and other small animals. They are known to be effective at controlling rodent populations, which makes them beneficial to farmers and homeowners. They are constrictors and kill their prey by suffocating them.
Black rat snakes are also known to be good at avoiding predators, and will often play dead or release a musky scent to deter potential predators. They are also known to be good at escaping from predators by climbing trees or other structures.
Black rat snakes typically hibernate during the winter months, typically in rock crevices, mammal burrows or hollow trees. They are known to be relatively solitary animals and are not typically found in large groups.
In the wild, black rat snakes can live for 15-20 years, and in captivity, they can live up to 25 years.
Habitat
Black rat snakes are found throughout much of the eastern and central United States, from southern New England to northern Florida and west to central Texas and the Dakotas. They are also found in parts of Canada, including southern Ontario.
Black rat snakes prefer wooded or rocky areas, and are often found near water sources. They are also commonly found around farms and outbuildings, as they feed on rodents such as rats and mice. They are known to be good climbers and are often found in trees and on buildings.
They are known to be adaptable to different habitats, and can be found in a wide variety of environments, including forests, fields, wetlands, and suburban areas. They are also known to be able to survive in areas that have been disturbed by human activity, such as roadsides, abandoned buildings, and residential areas.

Habitat loss is a significant threat to black rat snakes, as well as over collection for the pet trade. They are considered a threatened species in some areas and conservation efforts are being made to protect their habitat.
Diet
Black rat snakes are opportunistic feeders and will eat a wide variety of prey. Their diet primarily consists of small mammals, such as rodents, as well as birds and their eggs, lizards, and frogs. They are known to be effective at controlling rodent populations, which makes them beneficial to farmers and homeowners.
Black rat snakes are constrictors, meaning they kill their prey by suffocating it. They use their sharp teeth and powerful body to grab and hold onto their prey, and then wrap their body around the prey to constrict it. Once the prey has stopped moving, the snake will swallow it whole.
They are also known to be opportunistic eaters, and have been known to eat a wide variety of prey, including small mammals, birds, reptiles, and fish. Black rat snakes have been observed preying on small mammals like mice, voles, and shrews, and also eating young rabbits, squirrels, and chipmunks. They also eat reptiles like lizards and young snakes, birds, eggs, and fish.
In captivity, black rat snakes can be fed with mice, rats, and other small rodents. They should be fed every 7-10 days and it is important to provide a fresh water source at all times.
Predators, Threats, Conservation, and Population
Black rat snakes have a number of natural predators, including birds of prey, such as hawks and owls, as well as larger snakes and mammals, such as raccoons, foxes, and skunks.
Habitat loss and fragmentation is a major threat to black rat snakes, as it reduces the amount of suitable habitat available for them to live and breed. Other threats include overcollection for the pet trade, road mortality, and pesticide use, which can reduce the availability of prey for the snakes.
Black rat snakes are considered to be a threatened species in some areas, and conservation efforts are being made to protect their habitat and reduce threats to their survival. This includes protecting and restoring their natural habitats, creating wildlife corridors to connect isolated habitats, and reducing pesticide use in areas where they are found.
The population of the black rat snake varies widely depending on location, but overall the species is considered to be abundant and not globally threatened. They are widely distributed across the eastern and central United States, and are common in many parts of their range. However, in some areas, their population has declined due to habitat loss and overcollection for the pet trade.
It is important to note that, as with all wild animals, it is illegal to capture or keep them as pets without proper permits. The black rat snake should be left alone in the wild.
Reproduction, Babies, and Lifespan
Black rat snakes typically breed in the spring, and the females lay their eggs in June or July. The females will lay a clutch of 6-30 eggs, depending on their size and overall health. The eggs are usually laid in a hidden location, such as a hollow tree or a rock crevice, to protect them from predators.
The eggs will hatch in approximately 6-8 weeks, and the hatchlings are typically 6-12 inches in length. They are brown or gray in color, with dark brown or black blotches on their back. As they mature, they will eventually turn black.
Black rat snakes are relatively independent from birth and do not receive any parental care. The young snakes are on their own to find food and shelter. The young snakes will typically reach maturity at 3-4 years of age.
In the wild, black rat snakes can live for 15-20 years, and in captivity, they can live up to 25 years.
