Discussion This commonly heard frog of the Pacific coast, active both day and night, is found from sea level to over 10,000' (3,000 m). When Hollywood moviemakers need an authentic outdoor nighttime sound, they often record its call. As a consequence, the Pacific Treefrog has been heard around the world. This species is sometimes placed in the genus Hyla.
