摘要
2009年3—7月,在北京小龙门森林公园悬挂人工巢箱,对大山雀(Parus major)和褐头山雀(P.montanus)的繁殖进行比较研究。野外共悬挂100个巢箱,其中19巢(19.0%)被大山雀、11巢(11.0%)被褐头山雀进驻,总利用率为30.0%。同域繁殖的大山雀和褐头山雀在窝卵数、孵化期上有极显著差异(P<0.01),其中大山雀的窝卵数(8.21枚±0.25枚,n=19)极显著大于褐头山雀(6.18枚±0.23枚,n=11),而褐头山雀的孵化期(14.22 d±0.44 d,n=10)极显著长于大山雀(13.17 d±0.83 d,n=12)。两者在卵重、卵大小、出雏数、雏鸟出飞数上无显著差异(P>0.05)。大山雀的繁殖成功率(27.0%)和营巢成效(63.2%)均显著低于褐头山雀(54.5%和100%)(P<0.01)。表明大山雀可能采取高产卵数、低存活率的繁殖对策,而褐头山雀的繁殖策略则可能为低产卵数、高存活率。
From March to July 2009,an investigation was conducted to compare the reproductive parameters of Great Tit（Parus major） and Willow Tit（P.montanus） in artificial nest boxes in Xiaolongmen forest park of Beijing.A total of 100 nest boxes were hung at forest edge,19 and 11 of which were occupied by P.major and P.montanus,respectively.The clutch size of P.major （8.21±0.25 eggs,n=19） was much larger than that of P.montanus（6.18±0.23 eggs,n=11）,but the hatching period of P.major（13617±0.83 d,n=12） was shorter than that of P.montanus（14.22±0.44 d,n=10）（P〉0.01）.There were no significant differences on the egg mass,egg size,nestling success,and fledging success between the two tit species （P〉0.05）.The nesting success of P.montanus（54.5%,n=11） was much higher than that of P.major（27.0%,n=19）.It was suggested that P.major could have higher clutch size but lower fledging success,while P.montanus could have lower clutch size but higher fledging success.
