Wandering Garter Snake
They are commonly found in freshwater wetlands or riparian habitats, and are excellent swimmers.
This snake typically feeds on fish, amphibians, small mammals, birds, insects, snails, worms, and leeches, which they find on the ground or in the water.
Found in Colorado, they have a lighter color (grey/brown) with a yellow/white mid dorsal stripe.
Unlike other snake species which lay eggs, garter snakes give birth to 10-40 live young at a time.
When they are threatened, they secrete a chemical from that they rub on themselves and the perceived threat.
