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 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.

This toad's call is a prolonged high-pitched musical trill, lasting up to 10 seconds, which is produced at night .
