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.
This is a 21 second recording of the advertisement calls of several Great Plains Narrow-mouthed Toads calling at a close distance from a small pool in a creek in Santa Cruz County, Arizona in August at night. Insects can be heard in the background.
This is a very short recording of a single call from one toad in the same group of toads.
