个性的个体差异会影响在新的或具有挑战性的情况下的行为。人格特质可能会受到选择，因为它们会影响支配他人的能力。我们调查了在冬季饲养表的优势等级是否与大山雀，山雀的自然种群中的可遗传的人格特征（通过在新环境中的探索行为来测量）相关。我们提供了成群的资源，在饲养表和计算线性优势层次的基础上的观察之间的二对色环的个人，我们使用了一个实验程序来衡量这些鸟类的个人探索行为。我们发现，快速探索领域的男性有更高的优势排名比缓慢探索领域的男性在两个三个样本，和优势呈负相关的观察站点和领土之间的距离。相比之下，快速探索nonterritorial青少年有较低的优势等级比缓慢探索nonterritorial青少年，这意味着在野外的优势和个性之间的关系是依赖于上下文的。我们将讨论如何在优势这些模式可以解释早期报道的影响，鸟类的个性出生的扩散和健身。
Individual differences in personality affect behavior in novel or challenging situations. Personality traits may be subject to selection because they affect the ability to dominate others. We investigated whether dominance rank at feeding tables in winter correlated with a heritable personality trait (as measured by exploratory behavior in a novel environment) in a natural population of great tits, Parus major. We provided clumped resources at feeding tables and calculated linear dominance hierarchies on the basis of observations between dyads of color-ringed individuals, and we used an experimental procedure to measure individual exploratory behavior of these birds. We show that fast-exploring territorial males had higher dominance ranks than did slow-exploring territorial males in two out of three samples, and that dominance related negatively to the distance between the site of observation and the territory. In contrast, fast-exploring nonterritorial juveniles had lower dominance ranks than did slow-exploring nonterritorial juveniles, implying that the relation between dominance and personality is context-dependent in the wild. We discuss how these patterns in dominance can explain earlier reported effects of avian personality on natal dispersal and fitness.
