Green Frogs Calling

Male green frogs have recently started calling their rather explosive loose banjo string call. Sometimes there is a single note, or often several are issued. Scientists have actually differentiated six different calls. Green frogs have paired vocal sacs which act as resonating chambers, as do the wood frog, northern leopard and pickerel frogs. Unlike American toads, spring peepers, bullfrogs and gray treefrogs, whose single pouch bubbles out beneath their chins when they call, the inflated pouches of the green frog aren’t that obvious. There is a slight swelling of the throat and sides of its body when it is calling, which you can hopefully detect in the accompanying photograph.
