Abstract
Personality differences measured under standardized lab-conditions are assumed to reflect differences in the way individuals cope with spatio-temporal changes in their natural environment, but few studies have examined how these are expressed in the field. We tested whether exploratory behaviour in a novel environment predicts how free-living individual great tits (Parus major) react to a change in food supply. We temporarily removed food at feeding stations during two summers and recorded the behavioural response of juvenile birds to these food manipulations using radio-tracking. When challenged by an abrupt change in food supply, fast-exploring individuals more rapidly switched to different foraging areas at longer distances from the feeder. This study is the first to show that personality traits predict the spatial response to experimentally induced changes in their natural environment.
