Table 3. Direction and strength of changes in behaviour after experimental presentation, and whether the observed behavioural change supports the threat sensitivity hypothesis.

Vocal responses are displayed on a log scale, and probability of travelling and being visible are on a logit scale so standard errors can be displayed. Significant changes in behaviour are shown in bold.
