使用2种不同的操作性非匹配任务测试了4种种子缓存乌鸦的性能。这些物种不同，他们的依赖储存的食物，空间记忆测试的差异已与更好的性能更依赖缓存的物种，收购和保留的颜色不匹配的样本任务进行了测试实验1。采集的颜色任务是不相关的缓存的依赖性，并在内存testings.Acquisition和保留的操作性空间非匹配到样本的任务进行了测试，在实验2中的性能物种之间没有差异。在空间任务的物种差异被发现收购和保留测试。自然历史对记忆进化的影响进行了讨论。
The performance of 4 seed-caching corvid species was tested using 2 different operant nonmatching tasks. These species differ in their dependence on stored food, and differences in spatial memory tests have been correlated with better performance by the more cache-dependent species, Acquisition and retention of a color non-matching-to-sample task was tested in Experiment 1. Acquisition of the color task was not correlated with cache dependence, and no differences between species in performance during memory testing were found. Acquisition and retention of an operant spatial non-matching-to-sample task was tested in Experiment 2. Species differences in the spatial task were found for acquisition and during retention testing. The influence of natural history on the evolution of memory is discussed.
