WOOD FROG

(Rana sylvatica), terrestrial frog (family Ranidae) found from the southeastern United States to Alaska. In the United States and parts of Canada the wood frog generally inhabits damp woodlands; in the north it frequents areas that, in spring, are supplied with water for breeding. The wood frog can change from yellowish to pink, brown, or blackish. A dark facial mask is present but not always immediately noticeable. Maximum length is approximately 8.25 cm (3.25 inches). The voice is a ducklike quack.
