Antipredator behavioural compensation of proactive personality trait in male Eurasian siskins

Many animals show behavioural syndromes (i.e. suites of correlated behaviours across multiple situations). These behavioural correlations, however, imply limitations in the behavioural plasticity of individuals when facing the trade-off between predation risk and starvation risk. Some models suggest...

In this study we tested these two alternative hypotheses with wild wintering Eurasian siskins, Carduelis spinus, foraging at artificial feeders. Male siskins have a melanin-based black bib that has been found to be correlated with exploratory behaviour, aggressiveness and dominance, and therefore is a signal of proactivity. We found that male siskins with large black bibs uttered more distress calls upon capture and displayed a vigilance strategy that improved predator detection. Moreover, this vigilance strategy did not reduce food intake rate. These results show that proactive individuals are not reckless, but instead compensate for their personality trait with stronger antipredator behaviours, and thus, do not necessarily have to pay a predation cost. Our results support the view of a positive relationship between eumelanism, proactive personality and the display of antipredator behaviours.Association for the Study of Animal Behaviour2014info:eu-repo/semantics/articleinfo:eu-repo/semantics/acceptedVersion18 p.application/pdfhttp://hdl.handle.net/2072/355949https://doi.org/10.1016/j.anbehav.2014.02.002RECERCAT (Dipòsit de la Recerca de Catalunya)reponame:Recercat.
