摘要: Studies on the relationship between behavioral traits and dispersal are necessary to understand evolution of syndromes. Empirical studies have mainly focused natal dispersal, even though differences dispersers philopatric individuals suspected hold through whole life cycle, potentially affecting breeding propensity. Using capture–mark–recapture data trials in a forest passerine, thorn‐tailed rayadito Aphrastura spinicauda, we describe inter‐individual exploratory behavior aggressiveness, investigate those dispersal. Our study took place Fray Jorge National Park, north‐central Chile, where relatively isolated population rayaditos inhabits naturally fragmented environment. We found that scores for were consistent years. Exploratory was similar sexes, while males showed higher levels aggression towards conspecific male intruder. Only related propensity, with fast‐exploring being more likely dispersed seasons. This finding provides indirect evidence existence strategy could reduce costs landscape Jorge. To our knowledge, this is first documenting an association wild bird population. A longitudinal individual‐based will help determining whether constitutes syndrome.
