摘要: Animal personality has been linked to individual variation in both stress physiology and social behaviors, but few studies have simultaneously examined covariation between traits, hormone levels, behaviors free-living animals. We investigated relationships exploratory behavior (one aspect of animal personality), physiology, foraging wild house finches (Haemorhous mexicanus). conducted novel environment assays after collecting samples baseline stress-induced plasma corticosterone concentrations from a subset finches. then fitted individuals with Passive Integrated Transponder tags monitored feeder use interactions at radio-frequency identification equipped bird feeders. First, we found that higher exhibit more environment. Second, interacted unique conspecifics the wild, though this result was stronger for female than male Third, were quick begin exploring frequently slow-exploring individuals. Finally, unrelated including amount time spent on feeders, previously shown be predictive acquiring bacterial disease causes annual epidemics Overall, our results indicate differences are network traits Such important implications finch ecology, as can contribute fitness wild.
