摘　　要：在吉林省左家自然保护区山地次生林中,利用人工巢箱招引白眉姬鹟,进行了其身体条件对繁殖投入的影响研究.结果表明:白眉姬鹟雌鸟身体条件与首枚卵产期、窝卵数及巢材重量投入无显著相关性;雄鸟身体条件与首枚卵产期呈显著负相关(r=-0.525,P<0.001),与窝卵数呈显著正相关(r=0.312,P=0.029);雌鸟身体条件与孵化期坐巢时间呈显著正相关(r=0.367,P=0.013);雌雄鸟身体条件与递食次数无显著相关性,但亲鸟育雏次数随窝雏数增加而显著增加(r=0.552,P<0.001).研究表明白眉姬鹟可根据自身和配偶身体条件调整繁殖投入.This paper conducted a study on the effects of body condition on reproductive investment in the Yellow-rumped Flycatchers（Ficedula zanthopygia） inside artificial nest box in secondary-forest of Zuojia Nature Protection area in Jilin Province during March to July in 2014--2015. The results indicated that female body condition had no significant correlation with the laying time, clutch size and nest materials weight. Male body condition was negative correlation with the laying time（r=--0. 525, P〈 0. 001）, and positive correlation with clutch size （r = 0. 312, P = 0. 029）. The remarkable correlations between female body condition and incubating duration were found（r=0. 367, P= 0. 013）. Found that adult body condition had no significant correlation with brooding times. In addition, brood size was positive correlation with brooding times（r= 0. 552, P〈0. 001）. This study shows that Yellow- rumped Flycatchers can vary their reproductive investment according to their own body condition or their mate＇s body condition.
