摘　　要：2005年秋季,在哈尔滨针对圈养条件下的东北松鼠对松子、核桃、橡子、玉米和瓜子等9种植物种子的进食和贮藏开展了研究。结果表明,东北松鼠对各种植物种子的进食选择和贮藏选择具有很大的差异性;松鼠的饥饿状况、食物的适口性、营养成分、可保存性都会影响松鼠对种子的进食和贮藏,特别是进食所需时间和贮藏所需时间是影响到其进食选择和贮藏选择的主要因素。松鼠对各种植物种子进食与贮藏的选择体现了其高效合理的觅食策略。The selective feeding and storage of plant seeds by northeast squirrels （ Sciurus vulgaris mandchuricus ） in captivity was studied in autumn, 2005, in Harbin.Results showed that great differences existed in selectivity of squirrels toward different plant seeds. Factors influencing their selection were taste, foodstuff, duration of storage and, especially, the time required for their feeding and storage, also whether hungry. Results also reflected that their feeding strategy was effective and adaptive.
