Where & When to Spot

I usually see this snake species on visits to parks in early mid April during the first warmer days. With no vegetation yet, the snake is easy to spot. Also, they seem to be hungry and will be more active.

How to Identify

The variant here in around Montreal is dark grey to dark greenish with yellow stripes. As there are not many different snakes, not difficult to identify. In other words, if you see a snake in a park around Montreal, most probably it is a Common Garter Snake.
