Animals often encounter the problem of identifying the temporal structure of their species‐specific communication sounds amidst heterospecific signals that are more intense. Little information is available, however, concerning the effects of intensity on these discriminative capacities. Here we report that male frogs, Physalaemus pustulosus , are able to discriminate between sounds that differ only in their direction of frequency modulation and that this discrimination remains intact over their entire response range; more than a 10,000‐fold range in sound intensity in some cases.
