摘 要:2009年,我们利用人工巢箱在吉林省左家自然保护区次生林中对大山雀亲鸟营巢投入对繁殖功效的影响开展了初步研究。大山雀平均巢材重量为33.90±13.44 g,不同繁殖个体的巢材重量存在极显著差异(t=18.336,Sig=0.000),表明大山雀不同个体的营巢投入不同。大山雀种群内个体的繁殖时间存在明显差异(Z=1.422,Sig=0.35),但巢材重量与大山雀产首枚卵日期间不存在显著的相关关系,较晚繁殖的个体并未减少筑巢投入。大山雀巢材重量与窝卵数(r=0.292,P=0.034)和出雏数之间存在显著正相关关系(r=0.294,P=0.033),巢材越重,窝卵数越大,出雏数越多,表明大山雀能通过调节营巢投入增加窝卵数和提高出雏率。但巢材重量与雏鸟出飞数无显著相关性,说明可能存在其它生态因子影响大山雀育雏期的成功率。Abstract:In 2009 we conducted a study on the relafiomhip between parental investment during nest building and reproductive efficiency of Great Tit inside artificial nest box in a secondary forest at Zuojia Natural Reserve,Jilin Province. The average weight of nest material was 33.90 ± 13.44 g. There existed significant difference in nest material weight among different reproductive individuals, which showed that different individuals of the Great Tits made different nest building investment. The breeding time of the Great Tit varied significantly. But there was no significant correlation between nest material weight and the initial egg date, and later breeding individuals did not reduce nest investment. There existed significant positive correlation between nest materials weight and clutch size ( r = 0.292, P = 0.034 ) and nestling size ( r = 0.294, P = 0.033), and the heavier the nest material ,the bigger the clutch size,and the more the hatching, which indicated that the Great Tit could adjust clutch size and hatching rate by increasing nest building investment. However, there was not an obvious correlation between nest materials weight and fledging size, which indicated that there maybe exist other ecological factors influencing fledging success of Great Tit.
