虽然人格已经在广泛的物种中得到了很好的研究，但相对较少的研究评估了标准化圈养测试中的行为是否可以预测野外行为。在2个繁殖群体周围捕获野生斑胸草雀，采用一种新的环境试验方法对其探索行为进行了研究。鸟类在野外的觅食行为也通过使用被动集成应答器标签系统来测量，以监测它们对喂食器的使用，喂食器定期在殖民地周围移动，以评估探索行为和社会性。在同一时期，在该地区使用的巢箱中监测了个体的繁殖成功率。我们发现，我们的社会性，野生和圈养探索的措施是可重复的，但与我们的预测相反，在新的环境测试中的探索与在野外探索饲养者没有显着相关。我们没有发现探索和社交之间的预测负相关，而是发现在新环境中的探索和社交之间存在显着的正相关。最后，我们发现几乎没有证据表明，我们测量的任何性格特征都会影响殖民地的繁殖成功，无论是单独的还是考虑到配对成员之间的个性相互作用。唯一的例外是，高度探索性的男性（野生饲养行为测定）更有可能比探索性较低的男性进行繁殖尝试。我们的研究结果表明，研究人员在使用经典的新环境测试等测试来推断野生人群的性格时应该谨慎。
Although personality has been well studied in a wide range of species, relatively few studies have assessed if behavior in standardized captive tests is predictive of behavior in the wild. We captured wild zebra finches around 2 breeding colonies and assayed their exploratory behavior with a novel environment test. The birds’ foraging behavior in the wild was also measured with the use of a passive integrated transponder tag system to monitor their use of feeders that were periodically moved around the colonies to assess exploratory behavior and sociality. During the same period, individuals’ reproductive success was monitored at the nest-boxes being used in this area. We found that our measures of sociality, wild, and captive exploration were repeatable, but contrary to our predictions, exploration in the novel environment test was not significantly correlated with exploration of feeders in the wild. We failed to find a predicted negative relationship between exploration and sociality, instead finding a significant positive correlation between exploration in the novel environment and sociality. Finally, we found little evidence that any of our measured personality traits influenced reproductive success at the colony, either individually or when the interactions between the personalities of both members of the pair were taken into account. The only exception was that highly exploratory males (assayed with wild feeder behavior) were more likely to make breeding attempts than less exploratory males. Our results suggest that researchers should use caution when using tests such as the classic novel environment test to make inferences about personality in wild populations.
