{"data":[{"source":"bio.acousti.ca","id":"47617","topic":"behaviour","value":"Typically, the males produce their calling song in the evening and at night. In the re- corded males, the calling song consists of a long series of echemes, each echeme lasting for 426\u2013583 ms (mean \u00b1 SD 503.87 \u00b1 46.81 ms) and containing 8\u201310 syllables (mean \u00b1 SD 8.49 \u00b1 0.52) (Fig. 4). e recurrence rate is fairly 20\u201330 \/ minute, the echeme repetition period being 2122\u20132760 ms (mean \u00b1 SD 2408.28 \u00b1 197.71 ms). Syllables are quite short (39\u201354 ms, mean \u00b1 SD 47.28 \u00b1 4.1 ms) and consist of two distinct parts: a shorter, lower amplitude opening hemisyllable (15\u201320 ms, mean \u00b1 SD 17.55 \u00b1 1.64 ms) and a longer, higher amplitude closing hemisyllable (20\u201339 ms, mean \u00b1 SD 29.73 \u00b1 4.49 ms). Acoustic signal amplitude modulation pattern is increasing and decreasing in both the opening and closing hemisyllables. The detailed descriptive statis- tics of the song characters are presented in Table 1. e calling song has the dominant frequency components between 7 kHz and up to more than 45 kHz (45 kHz being the upper limit of microphone frequency response in our recordings), with a main peak at about 12 kHz in both opening and closing hemisyllables (Fig. 5).","topic_link":"http:\/\/rs.tdwg.org\/ontology\/voc\/SPMInfoItems#Behaviour","info_url":"https:\/\/bio.acousti.ca\/node\/47617"}]}
