It was a beautiful day at Deer Lake, and we saw several species of frogs, huge tadpoles, turtles, ducks and other critters. Unfortunately the turtles and some of the frogs are invasive species.
Here are a few shots:

Is this frog native or invasive? One fellow today said it was an invasive and I guess we have to study up on frogs to be sure.

These tadpoles were big -- at least 10cm long, and some were larger, making me doubt that they are native species.

Last but not least, a family of ducks. These ducklings were so accustomed to people you could almost touch them. Makes one wonder at their chances come hunting season!
