摘要: Oilbirds, Steatornis caripensis, live in colonies caves, within which they navigate by echolocation (Griffin 1953, Snow 1961). The sonar “clicks” of these nocturnal birds typically last about 40 to 80 ms and are emitted at repetition rates up 12/s. Most the acoustic energy lies beween 1 15 kHz. Sound during some clicks is continuous but other clicks, here referred as double divided a silent period lasting 20–30 into two brief bursts sound.
