The male inflates its vocal sacs and as it calls, the inflated sacs resonate the sound. Peeping reaches a crescendo on the warmest night but ceases if temperature drops below 30 degrees Fahrenheit. When ready to mate, females arrive and choose their mates. Often, males are so preoccupied with breeding that they will accidentally grab another male. A release call tells the offending suitor that he has the wrong partner.
Frogs also vibrate their bodies to shake off mistaken males.
Mating occurs in shallow pools. The male sits on the female's back and fertilizes the 800-1,300 eggs as she deposits them. The eggs, only a fraction of an inch long, are laid singly on underwater vegetation. Depositing eggs can take up to one day to complete. Once breeding is finished, peepers return to the trees.
