Table 2. – Pair-wise differences between mean proportions of attempts made to dishes providing different sensory cues, with 95% Bonferroni-corrected confidence intervals for each difference. If a confidence interval includes zero, the bats were equally likely to make feeding attempts at the two types of dish. Sensory cue comparison Confidence interval preferred dish p(visual cues) – p(visual/sonar cues) -0.04±0.17 no preference p(visual cues) – p(sonar cues) 0.16±0.14 visual p(visual/sonar cues) – p(sonar cues) 0.20±0.14 visual/sonar p(visual cues) – p(no cue) 0.24±0.12 visual p(visual/sonar cues) – p(no cue) 0.27±0.13 visual/sonar p(sonar cues) – p(no cue) 0.08±0.10 no preference 61
