Advertisement Calls An advertisement call is the most well-known call of a toad. It is produced by a male during the breeding season to attract females of his own species. It can also serve an agressive function to defend his calling site by warning rival males of his presence. Toads usually make the calls from in or around bodies of water that are suitable for breeding and egg laying. These calls can be heard during the evening and at night, and sometimes during daylight at the peak of the breeding season. |

Release Calls A release call is produced by a male frog or an unreceptive female frog when a frog or other animal (including a human hand) grabs it across the back in the position used for mating or amplexus. It's a frog's way of saying "Get off my back! Let go!" |
