西丛鸦（Aphelocoma californica）会贮藏易腐坏和不易腐坏的食物，它们在短时间和长时间的间隔后都能找回这些食物。当易腐坏的食物在找回时总是已经变质，与对照组（其贮藏的食物在找回时总是新鲜的）相比，西丛鸦会减少贮藏的易腐坏食物的数量，并增加不易腐坏食物的贮藏量。然而，当高度偏好的食物只有在长时间间隔后才变质时，西丛鸦会减少贮藏的不易腐坏食物的数量。这些发现从回顾性和前瞻性过程在贮藏控制中的作用方面进行了讨论。
Western scrub-jays (Aphelocoma californica) cached perishable and nonperishable food items, which they could recover after both short and long retention intervals. When perishable items were always degraded at recovery, jays decreased the number of perishable items cached and increased their caching of nonperishable items, relative to a control group whose caches were always fresh at recovery. Jays reduced the number of nonperishable items cached, however, when highly preferred food items were degraded only after the long retention intervals. The findings are discussed in terms of the role of retrospective and prospective processes in the control of caching.
