The effect of current social status (in trial 2) and previous behavioural responses (in the first novel arena test, i.e. ‘trial 1’) on the responses of male fowl in a novel arena test after social status was manipulated (i.e. ‘trial 2’). (a) Status in trial 2 (dominant males: filled circles, subdominant males: open circles) did not affect the proportion of males that were bold (i.e. males that entered the arena within 30 s), but previous boldness (x-axis) had a significant effect on boldness in trial 2 (y-axis). Males that were dominant in trial 2 (filled circles, solid line) were (b) more vigilant (i.e. had a higher frequency of time spent being vigilant), (c) more active (i.e. conducted more subarea transitions), and (d) more explorative (i.e. visited more subareas) compared with males that were subdominant (open circles, dashed line). At the same time, these behaviours were repeatable within individuals (demonstrated by a positive slope; table 2). (e) Social status in trial 2 did not affect crowing. The figures show transformed response variables (for transformations, see main text).
