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 in and 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 Xenopus laevis is a 2-part trill, about 1/2 second, repeated up to 100 times per minute. Males have no vocal sacs and call from underwater during the day and at night. Calls are only faintly heard in the air.



 
This is a 10 second recording of the advertisement call of a simgle male frog made underwater in the laboratory of John Gerhart, University of California, Berkeley, 1/25/94 by Carlos Davidson.
