摘　　要：2008—2009年3—7月在吉林左家自然保护区,利用人工巢箱对大山雀一次和二次繁殖的繁殖参数进行了比较,共分析了43窝一次繁殖和19窝二次繁殖的数据资料.结果表明:大山雀一次和二次繁殖过程中选择了明显不同的繁殖对策,一次繁殖的窝卵数明显高于二次繁殖,一次和二次繁殖的平均窝卵数分别为(11.79±1.34)枚和(8.89±1.73)枚;二次繁殖的筑巢期、产卵期、孵化期都短于一次繁殖;但一次繁殖和二次繁殖的巢材质量不存在显著差异;一次和二次繁殖的孵化率和出飞率无显著差异,平均出飞数分别为(10.40±2.29)只和(8.05±1.90)只.大山雀二次繁殖主要通过减少窝卵数和缩短筑巢期减短繁殖周期,二次繁殖能增加大山雀的年繁殖生产力.From March to July in 2008 and 2009,compared the reproductive parameters of the first and second broods in Great Tit using artificial nest boxes at ZuoJia Nature Reserve.The data used in the study were from 43 broods of the first broods and 19 broods of the second broods.Results showed that Great Tit selected different reproductive strategies in the first and second broods process.The clutch size for the first broods was significantly higher than the second broods.The average clutch size for the first and second broods were 11.79±1.34 and 8.89±1.73 respectively.The nest building period,laying period and incubation period of the second broods were shorter than the first broods,however,no significant difference was dectected in the nest material weight between the first broods and second broods.The hatching rate and fledging rate of the first broods and second broods were similar.The average number of fledged per nest was 10.40±2.29 and 8.05±1.90 respectively.Great Tit could shorten breeding cycle of the second broods by reducing the brood size and nesting period.The second broods could increase the annual fecundity of the Great Tit.
