Appearance

The Brown snake is a small nonvenomous snake native to North and Central America. Dorsally, these snakes are brown to gray in color with a lighter center stripe bordered by small black spots; ventrally, they are light brown or pink with small black dots at the ends of the ventral scales.

Distribution

Geography

Brown snakes are native to Southern Ontario and Quebec, most of the eastern half of the United States, through Mexico, Guatemala, Honduras, and possibly El Salvador. These snakes live in different habitats including forests, riparian woodlands, wet meadows, savannas, grasslands, and wetlands. They are also common in urban areas.

Climate zones

Habits and Lifestyle

Brown snakes are generally solitary and can be found together only during hibernation or during the mating season. During cold winter months, they hibernate in communal dens usually in rocky outcrops or burrows of small rodents. These snakes are nocturnal and during the day they usually hide under logs, rocks, leaves and another cover. When they feel in danger, Brown snakes flatten themselves against the ground to appear larger and if picked-up release a foul-smelling musk.

Seasonal behavior

Diet and Nutrition

Brown snakes are carnivores; they primarily feed on slugs, snails, and earthworms. They may also consume other invertebrates such as sowbugs, mites, millipedes.

Brown snakes are polygynous which means that males mate with more than female during a single breeding season. These snakes mate in spring after emergence from hibernation. Females give birth to 3-31 live young in the late summer. Snakelets are born fully developed but usually stay with their mother for some time. They become reproductively mature at 2-3 years of age.

Population

Population threats

Population number

According to IUCN, the Brown snake is locally common and widespread throughout its range but no overall population estimate is available. Currently, this species is classified as Least Concern (LC) on the IUCN Red List and its numbers today are stable.

Ecological niche

Due to their diet habits, Brown snakes control populations of slugs, snails, and earthworms. They also serve as important prey species for local predators.
