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 call of the Boreal Chorus Frog is a slow but short rasping noise rising in inflection and lasting 1/2 - 2 seconds. The sound is similar to stroking the small teeth of a pocket comb.
