Fun Facts

  • Northern Brown Snakes are fairly tolerant of cold temperatures. They winter in dens, such as rodent burrows, rock crevices, or under buildings, that are below the frost line. These winter dens are often shared with other Brown Snakes, as well as with other snake species, including Garter Snakes, Northern Redbelly Snakes, and Smooth Green Snakes.
  • They are normally active during the day, but if daytime temperatures are too hot, the snakes will become nocturnal.
  • This harmless snake is non-venomous and does not bite. However, if handled or provoked, it can produce a strong musk odor from its anal glands.
