Individual variation in exploratory behaviour has been demonstrated in a diverse array of animal species. Understanding the evolutionary antecedents and ecological consequences of this variation is an active research area within animal behaviour. Here we investigate whether different exploration styles exhibited by black-capped chickadees (Poecile atricapillus) in a novel environment are related to how quickly these birds learn an acoustic discrimination task. We found that birds that readily enter a novel environment learn an acoustic discrimination task faster than birds that do not readily enter a novel environment. This result contrasts with previous work suggesting no correlation between exploration style and learning a spatial or associative task in great tits (Parus major), a close relative of the black-capped chickadee.
在各种各样的动物物种中,探索行为的个体差异已得到证实。了解这种差异的进化前身和生态后果是动物行为学领域一个活跃的研究方向。在这里,我们研究了黑头山雀(Poecile atricapillus)在新环境中表现出的不同探索方式是否与这些鸟类学习听觉辨别任务的速度有关。我们发现,容易进入新环境的鸟类比不容易进入新环境的鸟类学习听觉辨别任务的速度更快。这一结果与之前的研究形成对比,之前的研究表明,在与黑头山雀亲缘关系较近的大山雀(Parus major)中,探索方式与学习空间或联想任务之间没有相关性。
