DORISIANA SUTORI ( FIG. 6 )

Main traits of the sound communication of this species have already been described in Sueur (2000).

Seasonal rhythm. From March to May, end of the dry season.

Nycthemeral rhythm. From about 8.00 a.m. to 6.15 p.m.

Calling site and calling posture. Called on trunks or principal stems at heights of 5 m and up to the higher strata. During calling, males raised and moved their abdomen vertically and slightly lifted their wings.

Calling song. A long succession (10–45 min) of uniform echemes each composed of two syllables (A, B) with equal duration (length of syllable A: 0.027s ± 1.4 (0.024 –0.029, 35); length of syllable B: 0.027s ± 2.7 (0.020 –0.033, 35)) but with very distinct spectral features. Syllable A was sharply tuned with a dominant peak at about 2700 Hz. In contrast, syllable B was characterized with a broad high frequency band with the successive frequency bands of 2700 Hz, 4900 Hz, 5700 Hz, 6900 Hz, 8000 Hz and 17900Hz. Pulses of part A were fused while pulses of part B were produced at about 500 Hz repetition rate. Recorded at 40 m with obstacles, part B was almost completely degraded while the part A was poorly degraded.

Behaviour. Solitary, called once and flew to another calling site.
