{"data":[{"source":"bio.acousti.ca","id":"57378","topic":"behaviour","value":"Six records from one male were examined. The calling song consists of phrases (Figure 3B) with irregular intervals. Phrase durations vary between 1.69 and 2.31 s (1.94 \u00b1 0.13), and each phrase contains 71\u201382 syllables (74.6 \u00b1 2.9). The phrase starts with 7\u201310 lower amplitudes syllables (generally corresponds to 1\/7\u20131\/8 of phrase) and continues with a crescending sequence and reach as highest amplitude at the end of this part (Figure 3C). The remaining syllables have quite similar amplitude. The phrase begins with an isolated first hemisyl- lable and is followed by a gap which last 27\u201358 ms (41.15 \u00b1 9.97) between the first hemisyllable and the ordinary syllables in phrase. Oscillographic analyses show that the syllable periods duration varies between 20.44 and 31.81 ms (24.67 \u00b1 1.6), and each syllable shows a standard structure, which is formulated as loud and long opening hemi- syllable + less loud and short closing hemisyllable (Figure 3D). The opening hemisyllables duration varies between 7.82\u201317.78 ms (13.45 \u00b1 1.28), whereas the closing hemisyllable lasts for 8.73\u201315.90 ms (11.22 \u00b1 1.09).","topic_link":"http:\/\/rs.tdwg.org\/ontology\/voc\/SPMInfoItems#Behaviour","info_url":"https:\/\/bio.acousti.ca\/node\/57378"}]}
