Sounds of Pseudacris crucifer - Spring Peeper

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 Spring Peepers is a series of high-pitched single whistles repeated at about one second intervals. Occasionally there is a short trill.
