Abstract: The territorial song of Dendronanthus indicus in breeding season was analysed with computer acoustic analysis techniques. The bird's song had only one sentence pattern, composed of the four phrases repeated “jue zhi jù” syllables. Among these syllables, syllable of “jue” was the one with shortest duration(29.4±8.2ms), lowest frequency(MPF is 4120±156Hz)and broadest band-wide(BW -20dB =663±103 Hz). The “zhi” syllable had longest duration(260.4±20.4 ms), most narrow band-wide(BW -20dB =52±29Hz)and median frequency(MPF is 4841±39 Hz). The “jù” syllable had 121.4±15.7 ms duration and it's energy was mainly concentrated in 6244±53 Hz and the BW -20dB was 118±52 Hz. The duration of the whole sentence was about 2231±22 ms and the range of freqency was between 3816±57 and 6599±104 Hz. The territorial area was about 7848 m2 detected in the field using auditory feedback.
