Lowland Leopard Frog
Calling Male, Pima County, Arizona




Male frogs and toads sometimes make a variety of sounds. These calls can have different functions.


Advertisement Calls

The advertisement call is the most well-known call of a frog or toad. It is made by a male during the breeding season to establish his territory and repel rival males and to attract females as potential mates. Males usually make the call in or near bodies of water near areas that are attractive to a female as a good place to lay her eggs. Advertisement calls can be heard during the evening and at night, and often during daylight at the peak of the breeding season. Sometimes an advertisement call will be heard outside of the breeding season and away from water. The reason for this is not understood.

Each species has its own unique advertisement call. This is necessary to differentiate them when there is more than one species calling. The evolution of this specific male advertisement call and its recognition by females is considered to be an important isolating mechanism in the evolution of a species.


The call of the Lowland Leopard Frog consists of several short quiet chuckles, sounding like quick, short, kisses. Calls at night, sometimes during the day.

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.

The following sounds were recorded at night in Pima County, Arizona with the kind assistance of Dr. Cecil Schwalbe. The frogs called from an artificial pond which is part of a joint effort to re-establish Lowland Leopard Frogs near Saguaro National Park in areas where they were once more common.
