Discrimination of intermediate sounds in a synthetic call continuum by female green tree frogs

HC Gerhardt

Male Hyla cinerea produce two distinctive calls. Acoustically intermediate calls are rare. Females discriminate between synthetic intermediates that differ by one cycle of amplitude modulation (50 per second). Processing appears to be continuous. The tree frog's auditory system thus provides a wide margin for the discrimination of its two principal signals.
