动物在多大程度上受到同种动物的痛苦或痛苦的影响，将取决于它的移情能力。同理心很可能进化为便于父母照顾，所以目前的研究评估了鸟类是否会对针对它们的幼鸟的厌恶刺激做出反应。家鸡按平衡顺序暴露于两种重复的条件下：对照组(C；母鸡和雏鸡不受干扰)、对雏鸡吹气(APC，每30 S间隔对雏鸡吹气)、对母鸡吹气(APH，每30 S间隔对母鸡吹气)和有噪声对照(CN；S每30间隔吹气)。在每次测试中，在10分钟的预处理和10分钟的处理期间，对母鸡的行为和生理进行了测量。母鸡对APH和APC处理的反应是提高了警觉性，减少了整理行为，并降低了眼睛温度。在任何控制期内均未发生此类变化。心率增加和母体发声只发生在APC治疗期间，尽管雏鸟几乎没有发出痛苦的发声。观察到的明显和特定的反应表明，成年雌性鸟类至少具有支持同理心的基本属性之一。
The extent to which an animal is affected by the pain or distress of a conspecific will depend on its capacity for empathy. Empathy most probably evolved to facilitate parental care, so the current study assessed whether birds responded to an aversive stimulus directed at their chicks. Domestic hens were exposed to two replicates of the following conditions in a counterbalanced order: control (C; hen and chicks undisturbed), air puff to chicks (APC; air puff directed at chicks at 30 s intervals), air puff to hen (APH; air puff directed at hen at 30 s intervals) and control with noise (CN; noise of air puff at 30 s intervals). During each test, the hens' behaviour and physiology were measured throughout a 10 min pre-treatment and a 10 min treatment period. Hens responded to APH and APC treatments with increased alertness, decreased preening behaviour and a reduction in eye temperature. No such changes occurred during any control period. Increased heart rate and maternal vocalization occurred exclusively during the APC treatment, even though chicks produced few distress vocalizations. The pronounced and specific reaction observed indicates that adult female birds possess at least one of the essential underpinning attributes of empathy.
