In wild vertebrates, conspicuousness often signals a high phenotypic quality and is therefore associated with fitness benefits ("the handicap principle hypothesis"). However, conspicuous individuals usually face a higher risk of predation because they are easier to detect. Therefore, conspicuous individuals are expected to modify their behavioural and their physiological stress responses to limit the negative effect of their conspicuousness on survival. We examined the link between plumage… CONTINUE READING
