Advertisement Calls

An advertisement call is the most well-known call of a frog. It is produced by a male during the breeding season to attract females of his own species. It can also serve an agressive function to defend his calling site by warning 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 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, if at all.

This is a 1 minute 16 second edited recording of the fairly close calls of African Clawed Frogs recorded underwater in a small pond in Los Angeles County with an underwater microphone. These recordings were made on a sunny afternoon. The recording is an edit of 5 different calls from 5 different parts of the pond, presumably from 5 different frogs, though no frogs could be seen. Assorted mysterious underwater sounds are also heard in the background.

This is a 3 minute edited recording of distant calls of African Clawed Frogs recorded underwater in a small pond in Los Angeles County.These recordings were made on a sunny afternoon. 6 different calls are edited together. Assorted eerie underwater sounds are also heard in the background.

This is a 2 minute 30 second unedited recording of African Clawed Frogs recorded underwater in a small pond in Los Angeles County with an underwater microphone. These recordings were made at night, on the same day as the previous daytime recordings. More frogs are calling simultaneously and more continuously at night at the same location than they did in the daytime. Really weird otherworldly underwater sounds are also heard in the background.
