Figure S1 - Sounds Scary? Lack of Habituation following the Presentation of Novel Sounds

Summary of five Principal Components (PC) factor scores derived from ethograms of nine kangaroo behaviors in response to playback of different auditory signals. In experiment 1 (a. left panel), single playback of four auditory signals was trialed (raven call, hiss, foot stomp and whip crack). In experiment 2 (b. central panel), repeated playback of the foot stomp and whip crack signals was tested (12x/min for minutes 2 and 3). In experiment 3 (c. right panel), varying rate of playback of whip crack was tested (treatments were broadcast at 2x/min, 4x/min and 20x/min for 2 min). Because the PC factor scores were calculated for all trials together, the scales of each PC factor are relative across the three experimental treatments. Values are mean ± 1SD.
