四种山雀（沼泽山雀，Parus palustris；煤山雀，P. ater；蓝山雀，P. caeruleus；大山雀，P. Major）和一种雀类（绿翅雀，Caruelis choris）在径向迷宫的开放场地模拟中进行了比较。山雀物种之间在习得或渐近表现方面没有差异。随着经验的积累，绿翅雀的进步不如山雀。当强制选择四个球门框和自由选择所有八个球门框之间的保留间隔在 30 秒到 24 小时之间变化时，性能随着间隔的增加而下降。 24小时后，一些个体的表现仍然高于偶然性，并且储存食物的山雀（沼泽山雀和煤山雀）组合起来高于偶然性，而非储存性山雀（蓝色山雀和大山雀）则不然（这主要是由于大山雀的表现不佳）。研究结果与储存食物的山雀具有专门的空间记忆的假设相关联进行了讨论。
The performance of four species of tit (marsh tit, Parus palustris; coal tit, P. ater; blue tit, P. caeruleus; and great tit, P. major) and one finch (greenfinch, Carduelis choris) was compared in an open field analogue of the radial maze. There were no differences between the tit species in either acquisition or asymptotic performance. The greenfinch showed less improvement with experience than the tits. When the retention interval between forced choice of four goal boxes and free choice of all eight was varied between 30 sec and 24 hr, performance declined with increasing interval. After 24 hr some individuals still performed above chance, and the food-storing tits combined (marsh and coal tit) were above chance, whilst the non-storers (blue and great tits) were not (this was primarily due to the poor performance of great tits). The results are discussed in relation to the hypothesis that food-storing tits have a specialized spatial memory.
