Growing to 91 to 137 centimetres long, the eastern foxsnake is the second largest snake in Ontario. It is often confused with other blotched snake species, including the Massasauga rattlesnake, due to its similar colouring. This species feeds on small mammals and birds. While it simply swallows baby mice, nestlings and bird eggs, these snakes squeeze larger prey to death before eating it. Although eastern foxsnakes are considered terrestrial, these reptiles not only live close to water, they frequently swim from one location to another.
