Behavioural responses in behavioural assays of future dominant and subordinate male fowl.

<p>Males that later became dominant (filled dots) were (a) more explorative compared to males that later became subordinate (open dots, Exploration score is presented as SD units, see text for further explanation). There was no difference in (b) the number of crows uttered or (c) general vigilance in the novel arena test between future dominant and subdominant males. Future dominant males (d) remained vigilant for a longer period of time after a startle (a playback of conspecific warning call). Mean values ± SE are given. *p<0.05.
