Wood Frog (Rana sylvatica)

species distribution map JPG -- Species Photo

Wood frogs have a characteristic dark mask around the eyes. There is a great variation in the color of the wood frog--from pink, to brown, to black. No matter what color is described the dark mask is always present.

Wood frogs are found near moist woodlands, and they are very reclusive. In the winter they hibernate under dead logs, piles of rocks, and dead leaves. In the spring they are one of the first frogs to emerge from hibernation. Breeding takes place in small ponds and coulees. Their diet includes insects and worms.

These frogs are found farther north than any other frog. They have been found in shallow ponds in the Canadian tundra.
