Cute Frog of the Week: January 31, 2011
Don’t get confused if you hear a quack and there isn’t a duck in sight. You might’ve just heard the call of the wood frog, whose duck-like quack can be heard coming from moist wooded areas and ponds throughout the Northern United States, Canada and Alaska. If you see a small brown frog with a dark eye mask in the woods, it is likely to be a wood frog. There are no other species with a similar appearance in North America. This cute masked creature measures from 1-2 ¾ inches long and its color varies with temperature and gender; female wood frogs are often larger and redder. Reproduction takes place in late winter/early spring at ponds where there may often still be a layer of ice—but don’t worry about these frogs freezing! Unlike most other frogs, wood frogs can tolerate the freezing of their blood and other tissues. These frogs can survive many freeze/thaw events during winter, allowing up to 65 percent of their total body water to freeze. Cool, eh?
