Calling Male, Pima County, Arizona

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 following recordings were made at dusk and at night at a small pool in a canyon bottom in Yavapai County, Arizona (shown below at dusk.) Water was slowly flowing into the pool. 3 or 4 frogs were calling. Calling was not continuous and loud calling appeared to have been triggered by the loud trilling of Red-spotted toads.

This is a 25 second continuous recording of two frogs calling at night.

This is a 36 second edited recording of frogs calling at night. Bird noises are in the background.

This is a 56 edited recording of frogs calling at dusk. Bird notes, a poorwhill, mourning doves, and the distant echoed braying of wild donkeys are heard in the background. Red-spotted toads begin to call at the end of the recording.
