【摘要】 对斑啄木鸟Piciodes major japonicus大次生林中的巢位选择和繁殖成效做了研究.结果表明,斑啄木鸟巢位选择的主要因子是5m范围内树的基面积、巢树位置坡度和洞口纵径.生境选择的主要因子是上层植物盖度和下层植物盖度,以及5m内的基面积(F=4.15,P<0.01).据30巢观察,繁殖成功为22巢,占73.33%,失败巢8个,占26.67%.失败的巢中,人为破坏3巢,花鼠侵占2巢,自然失败的3巢.说明繁殖成功率较高.更多还原

【Abstract】 This paper was studied in the natural protective areas of Zuo Jia, Tilin Province in 1992-1997. The nest-site selection was divided into two parts : Habitat and cavity selection.The result was: Cavity entrance vertical diameter, Basic areas of 5-radius circle of tree species and slope of nests species was importanted nest-site selection. Hiegh of cavity entrance to ground cavity entrance orientation, and tree diameter at cavity entrance were the mast important nest cavity variables. Cavity entrance upper vegetation cover, habitat variables. The cavity variables were more important Han Hre habitat ones. According to 30 nests, breeding successful were 22nests, unsuccessful nest sites in 8 nests.更多还原
