Bioacoustics of Guyalna viridifemur

Flying song Not observed. Calling song Composed of two distinct sessions. The first consists of short echemmes, 11.8 ± 6.7 (4–22) in total, lasting about 0.11 ± 0.03 (0.07–0.16) each. Following each short echemme, there is an interval of 1.02 ± 0.8 (0.68–2.8) seconds. The second part comprises a long echemme, lasting approximately 6.16 ± 2.69 (4.9–12.26) seconds. The second part is emitted continuously by males as a chorus signalling. The signal presents frequencies distributed in broad-range frequencies of F1, F2, F3, and F4. The F1 is at 4.5 ± 0.08 (4.4–4.6) kHz, F2 at 6.61 ± 0.61 (5.8–7.3) kHz, F3 at 10 ± 0.89 (9.07–11.1) kHz, and F4 at 12.3 ± 1.52 (11.1– 14.3) kHz. Strell call A series of long-duration echemmes, but there is no defined rhythm as this signal depends on the organism’s stress level. The signal presents frequencies distributed in a broad-range frequencies of F1, F2, F3 and F4. F1 is at 4.04 ± 0.22 (3.8–4.2) kHz, F2 at 10.46 ± 0.2 (10.1–10.5) kHz, F3 at 13.31 ± 0.55 (12.2–13.9) kHz and F4 at 15.45 ± 0.9 (13.7– 16.6) kHz.
