Sounds of Rana berlandieri - Rio Grande Leopard Frog

Advertisement Calls

An advertisement call is the most well-known call of a frog. It is produced by a male frog in order to attract females during the breeding season and to warn other 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. Calls at night.

The following advertisement calls and accompanying sounds were all recorded at night from the side of the Colorado River in Imperial County (at the location shown to the left.) Several frogs were calling from the edges of the river. The sounds of a small dam and flowing water are heard in the background.
