{"data":[{"source":"bio.acousti.ca","id":"57300","topic":"behaviour","value":"Call recorded by Jos\u00e9 Vieira, the recording was made at 21:40 pm on July 14th, 2018 (air temperature not recorded). Adult male ZSFQ 933 (recording code: LBE-C-048). Calls are produced in series. Each series contains four to 34 calls (mean = 12.2 \u00b1 11.5; n = 6). Time between call series is highly variable, from 6.7 to 21.8 s (mean = 13.9 \u00b1 8.2; n = 4). The call sounds like running a thumb over a comb. Each call has a duration of 0.1\u20130.2 s (mean = 0.1 \u00b1 0.01; n = 16) and is markedly pulsed (10\u201313 pulses per call, mean = 11.6 \u00b1 0.8; n = 16). Each call is frequency modulated, with its dominant frequency slightly increasing through time. The dominant frequency at the beginning of each call is at 4,980\u20135,353 Hz (mean = 5,175.6 \u00b1 100.2; n = 16) and at 5,661\u20135,771 Hz (mean = 5,723.3 \u00b1 30.7; n = 16) at the end. In most calls, harmonics are visible; the first harmonic is at 9,865\u201311,475 Hz (n = 14), and the second harmonic is at 15,390\u201317,157 Hz (n = 13).","topic_link":"http:\/\/rs.tdwg.org\/ontology\/voc\/SPMInfoItems#Behaviour","info_url":"https:\/\/bio.acousti.ca\/node\/57300"}]}
