1. Two hundred and eighty-eight female green treefrogs responded in two-choice experiments using synthetic calls. The spectral properties of the sounds were similar; the fine-temporal properties were systematically varied. 2. Females preferred sounds in which the waveform periodicity was about 300/s, a rate typical of natural mating calls. They discriminated strongly against calls with periodicities of 100/s, 60/s and 50/s. Aperiodic calls and calls with periodicities of 225/s and 900/s were intermediate in attractiveness. 3. The results of four experiments indicated that periodicity preferences depended on corresponding changes in the amplitude-time envelopes of the signals. 4. Neurophysiological correlations and the implications of the behavioural results are discussed. 5. The biological significance in species recognition and in the differentiation of the mating call from other signals in the repertoire of the green treefrog is discussed.

1. Synthetic calls with a waveform periodicity of 300/sec and a bimodal spectrum attracted female green treefrogs as effectively as natural calls. 2. Effectiveness was markedly reduced if the relative amplitude of the two spectral peaks differed by as little as 10 dB. 3. Optimal frequency bands were 900-1100 Hz in the low range and 2700-3300 Hz in the high. 4. Addition of components at 1800 and 2100 Hz rendered the call less attractive. 5. In the absence of a bimodal stimulus, most females responded to a call containing a single spectral peak in the high or low range. 6. Mating call recognition in the green treefrog is compared with that in the bullfrog.
