Acoustic Repertoire of the Philippine Tarsier (Tarsius syrichta fraterculus) and Individual Variation of Long-Distance Calls
Table 1
Acoustic parameters of eight call types identified in the repertoire of the Philippine tarsier—start frequency (start ) (mean (±SD)) (Hz), minimum frequency (min ) (Hz), maximum frequency (max ) (Hz), duration (s), and number of notes contained in the call—mean (min-max) (*max reached above 22 kHz several times). It was difficult to measure min and max in distress call; therefore, only start (start of the fundamental frequency) and duration was measured. Numbers of analyzed calls (individuals) are given in each call type.
