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 California Treefrog is a quick low-pitched duck-like quacking that ends abruptly and is given repeatedly. Males call at night and during the day during the peak of the season, while sitting in water, usually near a rock. Males also produce a trilled encounter or warning call when interacting closely with other males of the species. (Davidson)
Unless otherwise noted, the following calls were all recorded at night at close range around a small artificial desert pond situated at the mouth of a large rocky riparian canyon in San Diego County. Male frogs were calling while floating on the water, hidden in reeds, and in the open.
