Among the passerine birds, species that store food have an enlarged hippocampal region (dorso-medial cortex), relative to brain and body size, when compared with the non-storers. The volume of one of the major afferent-efferent pathways (the septo-hippocampal pathway) is also greater in food storing species. This specialization of brain structure is discussed in relation to behavioural studies in which the spatial memory of storing and non-storing species has been compared.
在雀形目鸟类中，与不储存食物的物种相比，储存食物的物种相对于大脑和身体大小而言，其海马区（背内侧皮质）有所增大。在储存食物的物种中，主要传入-传出通路之一（隔-海马通路）的体积也更大。本文结合行为学研究讨论了这种大脑结构的特化，在这些行为学研究中，对储存食物和不储存食物的物种的空间记忆进行了比较。
