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 call of a Geat Basin Spadefoot is a short 1-3 note duck-like snoring sound. Compared to the sound of a flock of ducks slowed down. Calls at night.

This is a 13 second recording of the advertisement calls of one Great Basin Spadefoot at close range with a second in the background. The spadefoots were calling from a small temporary pool in an agricultural area of Franklin County, Washington at night in late May. Crickets, a barn owl screech, and farm equipment are heard in the background.		This is a 21 second recording of a distant chorus of a large group of Great Basin Spadefoots recorded at night in an agricultural area of Franklin County, Washington in late May.
