The Wood Frog (classified by scientists as Rana sylvatica) can be pink, tan, or even dark brown in color, but it is best identified by a black 'mask' around its eyes ending at the ears. This coloring matches the woods that the animal lives in, offering protection from preditors. It has a white or light yellow strip along its jaw and a white belly. The Wood frog is between 1 to 3 inches in length.

Wood frogs are found throughout North America, but they are the only frogs found north of the Arctic circle. It likes moist woods or tundra and, unlike most frogs, is not likely to be close to the water. Wood frogs eat all kinds of insects, especially spiders, beetles, common bugs, and snails.

However, the Wood frog will breed in temporary swamps and standing water after heavy rains in the early spring. Interestingly, this type of frog lays more eggs in the colder climates than in the warmer ones. This is often the best time to hear a Wood frog's call--it sounds very much like a duck! Females lay eggs in large clusters of over 400 that are covered in a sticky coating. Tadpoles hatch in a few weeks, and will leave the pool of water after 3 or 4 months.
