Abstract

Evaluation of the role of frequency spectrum, duration, temporal pattern of pulses and pulse form components in call discrimination behavior of H. regilla and H. cadaverina showed that pulse repetition rate is the only necessary component for effective discrimination. In each species the frequency of best hearing matches the dominant frequency of the call which optimizes detection of the calls but does not effect discrimination.
