Frogs and toads are more elusive than mushrooms to photograph while hiking but if you see the leaves move, it is worth a closer look. They are masters of camouflage, and to survive the cold they make an art out of it.
American Toads dig deep in the dirt, below the frost line, and hibernate until their world defrosts. Wood frogs, the kind we first hear peeping in early spring, have a kind of antifreeze in their blood that allows them to live as far north as the Arctic Circle. They can thaw their frozen parts after winter and live again. Bull frogs will even swim around under partially frozen lakes all winter.

Books about frogs and toads – my personal favorite is the Frog and Toad series, which Cap’n J loves to read himself. Not an information source, but fun stories that can get kids interested in these strange creatures.
