Communication and Perception
Greater roadrunners have a wide range of vocalizations. The song of G. californianus is a series of six slow, low coos in descending pitch. During the mating season males will also attract females with a whirring call. The alarm call is a clackety noise produced by clicking the mandibles together in a sharp and rapid manner. The chicks give a buzzing begging call.
