摘要
通过在天然次生林内悬挂巢箱的方法比较研究了大山雀在人工巢箱和天然巢洞的繁殖情况.结果表明,悬挂的113个巢箱中,有75巢大山雀筑巢成功并产卵孵化;与同一地点的19巢天然洞繁殖的大山雀的几项主要繁殖参数进行比较后发现,窝卵数、孵化率、出飞率和繁殖成功率不具有统计意义上的显著差异(T-test,P>0.05),但上述指标巢箱均优于天然洞,尤其体现在窝卵数大、生产力高、捕食水平低等方面.
113 Nest-boxes were placed in Zuojia natural protective reserve in Jilin Province.The breeding parameters of Great Tits were compared between nesting nest-boxes(n=75) and natural cavities(n=19).The results show: differences of several main parameters(clutch size,hatching rate,fledge rate and success rate) are not statistically significant(T-test,P〉0.05),but all of these parameters nesting nest-boxes are better than natural cavities.Especially,clutch sizes are lager and predation rate is lower in box nests than in cavity nests.
