Advertisement Calls

An advertisement call is the most well-known call of a frog. 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. Frogs 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.

The advertisement call of the Rio Grande Leopard Frog is a short, low-pitched trill or rattle, lasting less than a second, given singly or in rapid sequences of 2 - 3 trills, made at night. Chuckling sounds are also heard along with the trills. These sounds are probably associated with territorial behavior similar to encounter calls.

The following advertisement calls were recorded at night at an irrigation canal in Imerial County (shown below.)
