Reproduction and Mating Habitsa snake curled around a branch makes a person think of snake information

Some of the snake species that inhabit Maryland lay eggs and others give live birth. The female Eastern Rat Snake lays 6 to 24 eggs in mid to late July. The Eastern Garter Snake gives live birth to between 10 and 30 young from July through August. Both types of snakes usually lay eggs or give birth in secluded areas like burrows that are abandoned by other animals or in wood piles, the base of hollow trees, and leaf litter.

Most of the snake species in Maryland have the same mating habits and use the same mating techniques. Males will emit pheromones around their territory to attract females for mating and will mate with several different females during the same breeding period. Once the mating is over, the fertilization and incubation begin. Most females have a gestation period of two to three months before they lay eggs or before giving birth.

Feeding Habits

The type of foods that a snake eats depends on the environment that snake species inhabits. The Red Bellied Water Snake and the Northern Water Snake feed on frogs, fish, and other aquatic species. The Eastern Rat Snake and the Northern Black Racer feed on mice, small rats, bird eggs, birds, and other small mammals. Some of the smaller snake species such as the Eastern Garter Snake feed on earthworms, salamanders, slugs, insects, lizards, small fish, and some insects.

Northern Copperhead

Copperhead is the most common venomous snake that inhabits Maryland. They are found in fields, forests, swamps, rocky outcrops, and agricultural fields that border forest. Homeowners encounter these snakes in piles of firewood, fallen leaves, under decks, in flowerbeds, under swimming pool platforms, and under or around landscaping rocks.

Here is how to tell if you are dealing with a Copperhead:

The Copperhead is well-camouflaged, which allows it to blend in with a natural background. These snakes come out during the daytime to absorb the heat from the sun in early to mid-spring and early fall. During the hot summer months they typically lead nocturnal lifestyle to avoid the extreme heat of the daytime.

Copperheads and Humans

Before 2009, we had received an average of 2 calls per year from homeowners about Copperhead problems. In June of 2012, we removed 2 Copperheads from a backyard in Germantown, Maryland, 1 from a crawl space under a home in Edgewater, Maryland, 1 from under a deck in Westminster, Maryland, and 3 from two different back yards in Crownsville, Maryland.

This species is not very aggressive, but they will bite if they feel threatened. If a human would have frightened this Copperhead by stepping off the top step onto the bottom stone, they would most likely have been bitten on the foot or lower leg. Our technician safely removed this Copperhead and relocated it to a more appropriate area away from humans.

Copperhead venom is not usually deadly to a healthy adult human, however, it is painful and you must seek medical attention immediately. Young children, the elderly, and people with heart conditions are at a higher risk of death.

The Timber Rattlesnake inhabits the western counties of Maryland including Fredrick County, Washington County, Allegany County, and Garret County. On a very rare occasion, Timber Rattlesnakes have been seen in Carroll County, Baltimore County, and Harford County. This species prefers a rocky terrain in heavily forested areas.

Like all snakes, the Timber Rattlesnake is cold-blooded and is nocturnal during the hot mid-summer to avoid the high temperatures of the day. They hibernate in the same den year after year and typically stay in close range to their den site. Young Timber Rattlesnakes are sometimes found in flower beds and tall grass.

The Timber Rattlesnake is the only snake species in Maryland that has a rattle on its tail. They will bite when provoked or if they feel threatened. This species has very potent venom that can cause death if not treated immediately with the proper anti-venom.

Several issues contribute to the increased interaction between humans and Copperheads, including population increase of both humans and Copperheads, as well as housing that is being developed near forested areas. The weather also plays a huge part: warmer-than-normal winters mean fewer Copperheads freeze to death.

A healthy source of food also contributes to the increased population of Copperheads. Many homeowners living near or in a forested area are likely to have field mice on their property—one of the main food sources for Copperheads. Typically, they eat about once per week and spend the remainder of their time resting in a safe area away from predators.
