【摘要】 2004—2006年的3—7月,通过人工招引的方法对大山雀的窝卵数进行了研究.研究表明:人工巢箱内繁殖的大山雀的常见窝卵数为10—12枚,平均窝卵数为10.24±1.87枚(n=157巢),卵重为1.47±0.12克(n=484枚),卵大小为1.646±0.063cm×1.287±0.045cm(n=484枚).卵重差异显著(P<0.05),卵长径无显著性差异(P>0.05),卵短径差异显著(P<0.05).此研究方法为其它鸟类窝卵数的研究提供了一种参考.更多还原

【Abstract】 This paper studied the clutch size of the Great Tits from 2004 to 2006.The results show that the familiar clutch size of the Great Tits is 10-12 Entries in artificial nest-boxes,the average clutch size 10.24±1.87(n=157),the egg weight 1.47±0.12g(n=484),the size of the egg 1.646±0.063×1.287±0.045cm(n=484).the egg weight difference is prominence(P<0.05).The egg length pathway doesn’t exist significant difference,but the egg short pathway exists significant difference.The research means affords a sort of demonstration for other Aves investigation.更多还原
