It’s March 12th and time to tune our ears. Why? Not bird calls but frog calls. First of all we want to hear the “quack! quack! of that little masked guy, the wood frog. Timing several minutes important. They come to mate in the pond. It is a hectic time for it is a week to ten days that you hear the duck-like calls. Once mated they disappear in all directions for another year. Timing is important, eh. Like most frogs they can hear you coming on the Lower Trail. All is silence. Wait! Several minutes then comes a “quack” then another until there is another cacophany of sound. Hearing is believing. Later we hear spring peepers and the Chorus frogs – quite an spring orchestral sounds.
