Found: October 28, 2001 at School Street, in a layer of dead leaves in the flower garden.
Distinguishing characteristics: Wood frogs have a dark eye-mask and two ridges running from the eye all the way down either side of the back. Their color can vary from very dark brown to reddish brown. This one was pinkish-brown with a pale underbody.
Wood frogs make shallow burrows in the soil where they spend the winter. They generate antifreeze compounds which allow them to survive the temperature fluctuations.

If it looks like a frog, it hops like a frog, and it sounds like a duck it's a wood frog!
