Northern Brown Snake

This time of year, the lawns and gardens of Jamestown are buzzing with activity as people scramble to get their homes looking great for the summer season. At nighttime, after even the most die-hard gardeners have called it a day, something else takes over the job of protecting our gardens: the Northern Brown snake.

As the name suggests, the Northern Brown snake is a small brown snake that can be found in a variety of habitats across New York State. Although the majority of the snake is a shade of brown/grey, there is a lighter colored stripe that runs down the length of the snake’s back. On either side of the stripe are a series of black spots that also run the entire length of the body. The belly of the snake is lighter colored, usually a shade of white/pink.

The Northern Brown snake eats a variety of small animals, such as snails, slugs, earthworms, and beetles. Its jaws and mouth are even specialized to pull snails out of their shells so that they can be eaten. This makes these snakes a valuable addition to a garden ecosystem.

The prey of the Northern Brown snake generally live underground, and come out at night to feed. This means that the Northern Brown snake must also be active at night, and be able to find its prey below ground. To solve this problem, these reptiles have evolved to have a very powerful sense of smell, which is actually used more heavily than their sense of sight! Their eyesight is decent for daytime movement, but the use of a special organ in the roof of the snake’s mouth enhances their smell and allows them to pursue their prey even in low-light conditions.

Although the majority of snakes lay eggs, the Northern Brown snake gives birth to live young. The eggs are still present, but they continue to develop inside the body of the mother until they are ready to hatch. In New York, both water snakes and garter snakes also give birth to live young. The Northern Brown snake is also similar to its relatives in that it is non venomous, and is an excellent swimmer.
