Frog Chorus

The easy echos of our green aquatic friends fills the evening air, causing the subtle serene energy of the forest to pop and ascend like sparks from some enormous, crackling amphibian fire. Fasten your seatbelt and send yourself into the unique world of the frog. In many frog species only males call. They are able to recognize one another and can even distinguish between regional dialects. For example, male bullfrogs can recognize the calls of their direct territorial neighbors. By ignoring the calls of these neighbors they save energy, and only vocalize aggressively to an intruder’s call. When a frog must compete with hundreds or thousands of other frogs to be heard, together they perform a chorus call where each frog calls in turn, successively. The most important feature of the chorus is the shared pattern. Through this pattern, few individuals calls are drowned out. One frog’s call may be dominant and trigger the calls of the responding frogs in symphony. Interestingly, calling is linked to physical size and females may be attracted to more vigorous calls.
