Frogs extensively use vocalizations to find partners. Male frogs start their advertisement calls in the early spring and serve a few purposes to communicate a large amount of information with potential partners. In one pond there may be many types of frogs, but individual frog species have evolved to each have their own unique call so other frogs outside the pond can recognize the call of their species. Once two frogs of the same species find each other, the female assesses the quality of the male’s call. Within close range, the call tells the female the size, hormone levels, and overall fitness of the male suitor.
