The Northern Water Snake (Nerodia sipedon) is a species of large, nonvenomous snakes, in the family Colubridae and native to North America.
I came across this water snake on my hike to Decew Falls, in the St. Catharines region of Ontario. At first the snake was startled by my presence and made a hasty retreat.
However, the Northern Water Snake regrouped and returned and of course this piqued by interest.
Unbeknownst to me, I walked past a young Northern Water Snake basking on a log. No parent was going to leave their young to the mercy of a stranger or predator. So the adult water snake returned to protect its young. You can see the adult water snake giving me a wary stare.
