TABLE I.

Mean values ± standard deviations of the call parameters of O. pumilio in response to playback of experimental stimuli.

	During playback	7.53 ± 5.79	5.96 ± 4.46	10.39 ± 3.13	12.53 ± 5.24
	Post-playback	12.18 ± 3.94	13.08 ± 5.37*	10.07 ± 4.83	12.60 ± 4.12
Percent Time calling	Pre-playback	60.37 ± 15.64*	74.26 ± 13.54***	56.07 ± 10.14	64.82 ± 16.69
	During playback	32.46 ± 24.94	25.71 ± 19.24	44.79 ± 13.51	54.01 ± 22.61

Dominant frequency (kHz)	Pre-playback	4.74 ± 0.19	4.80 ± 0.15	4.64 ± 0.76	4.90 ± 0.18
	Post-playback	4.75 ± 0.19	4.69 ± 0.22	4.72 ± 0.31	4.84 ± 0.17*
First-call latency (s)	Pre-playback	26.82 ± 2.32	27.44 ± 3.73	26.40 ± 8.97	27.32 ± 3.93
	Post-playback	22.89 ± 7.38	19.64 ± 7.04***	17.31 ± 9.83	19.76 ± 5.95**

For call rate, call bout duration and percent time calling, measurements were taken for pre-stimulus playback, during stimulus playback and post-stimulus playback periods. We were unable to measure dominant frequency and first-call latency during stimulus playbacks, therefore only pre- and post-playback values were analyzed. For call rate, call bout duration and percent time calling, asterisks indicate the level of significance difference between pre-/post-playback periods and during playback periods, and for dominant frequency and first call latency, asterisks indicate the level of significance difference between pre- and post-playback periods
