Table 3. Flight behavior summary statistics according to experimental conditions and sound signal attributes.

Data show means ± SEM and 95% CI (given in brackets as “[lower boundary, upper boundary]”). Columns A and B group together all control flights and all treatment flights, respectively. Columns C–F provide the adjusted (treatment minus control) data for each type of sound signal separately.
