Voice: Advertisement call is a loud, two parted kreck-ek, or ribbit, often repeated many times. When Hollywood movie makers wanted frog calls to convey the feeling of night time outdoors, they recorded local Pacific Chorus Frogs. Consequently the "ribbit - ribbit" calls of this species have become the stereotypical frog call, even in regions where they don't occur.

Breeding: November to July in any type of still or slow moving water.
