It’s not easy, being a little frog. When a lot of other critters think “What’s for dinner?”, often you are their answer! Even your larger relatives can’t be trusted. Lately, I’ve spotted a Garter Snake (Thamnophis sirtalis) close to the ornamental pond on a couple of occasions. I wondered if he was looking for a froggy dinner. Garter snakes are good swimmers, but I had no evidence of him entering the water. Recently, RailGuy noticed this snake just emerged from the pond. The telltale coating of duckweed shows that he was indeed in the water, no doubt hunting for a meal.
Of course, Garter snakes are themselves popular food items for a range of predators from large fish, bigger snakes, birds including crows, hawks and herons, and many mammals. Although harmless to humans, they are very often victims of undeserved persecution, and are also killed by dogs and cats, lawnmowers, automobiles, and pesticides. Like the frogs they hunt, they suffer from the destruction of their habitat, including wetlands.

I guess Kermit had it right — “It’s not easy being green” — even if you’re a little snake covered with green weeds.
Sheri — I know — snakes eat frogs — but probably your pond will reach some kind of ecological balance. I sure hope the snake survives. — barbara
Louise, yes, it’s a wild life out there.
Barbara, the pond is too shallow for overwintering. It won’t be long before the frogs will have to find a spot with deep mud for the winter. Next year, the pond will start all over again from scratch. I hope the snake is okay too. He’s pretty safe from traffic and little boys here, at least.
