Prey evasiveness and masking noise jointly promote the ultrahigh call rate in echolocating bats

Description

Analysis data and code, along with additional supplementary materials for this manuscript include: ScriptFig1：Prey evasiveness determines the prominence of the terminal buzz in Hipposideros pratti. Recordings from a microphone array and high-speed cameras show that bats produced more frequent, longer, and higher duty cycle buzzes when capturing flying insects compared to stationary or inescapable prey. ScriptFig2：Background noise induces terminal buzz in Hipposideros pratti when pursuing inescapable insect larvae. Noise exposure increased the occurrence of terminal buzz and call amplitude, although the number of calls, buzz duration, and duty cycle remained unchanged. ScriptFig3：Background noise induces a buzz-like adjustment in Hipposideros pratti approaching a landing perch. Noise exposure reduced pulse intervals and increased call amplitude, but did not elicit a full terminal buzz. ScriptSI_FigS1-3: FigS1 Prey evasiveness and buzz behavior in Pratt’s roundleaf bats.
