摘要
The call of the male of Besdolus bicolor, produced by percussion or drumming, is described for the first time. It represents the first recorded and analyzed signal for the genus Besdolus. It consists of a repetition of two or three beat groups, with each group composed by two (rarely three) beats, and with very constant interbeat intervals and intergroup intervals (mean 0.037 seconds and 0.213 seconds, respectively). The call pattern exhibited by this species can be catalogued as an ancestral percussive signal.
