Fig. 3. Proportion of trials in which the bats detected the cavity entrance while in flight. Bars represent means ± s.e.m. of individual medians (N=11 bats). Tasks are abbreviated as follows: E, echolocation; VE, vision + echolocation; TE, temperature + echolocation; AE, acoustic cues + echolocation; OE, olfaction + echolocation. Significant results from post-hoc comparisons of bats' performance in the echolocation task (grey bar) with all the other four tasks are indicated (paired t-tests, Bonferroni corrected P-values: ^*P<0.05).
