Only spring peepers will follow the location of a spring peeper chorus. There is also a trill call thought to be for territorial spacing. A trill call tells an intruding male that he is getting too close to another. The males will breed when a female approaches closely. Spring peepers have external fertilization, which means that the male will release his sperm as the female lays her eggs.
Females lay single eggs or small clusters of eggs.
When they are done, it is believed that the females leave the pond. The males stay in the pond for a longer time. If you were a frog, you'd have to know the mating call of your kind. Right when the first frogs are calling, they also need to keep an eye to the sky. For some, the timing is just a coincidence.
