American Bullfrog
American Bullfrog

Our largest frog, the bullfrog has a voice to match both its size and its name. Heard individually it is easy to detect the familiar “chug-o-rum” call of the male bullfrog. A dense chorus of bullfrogs can sound like an agitated herd of cattle. Bullfrogs chorus in late-spring and early summer from marshes, ponds, river backwaters and the weedy margins of lakes.
