【摘要】 2004～2006年的3～7月,在辽宁省白石砬子国家级自然保护区,对杂色山雀(Parus varius)的繁殖及繁殖成功率进行了初步研究。结果显示,杂色山雀主要营巢于海拔400～900m的阔叶杂木林、针叶林及林缘地带;繁殖期在3～7月,其洞巢种类多样,筑巢期约15d;巢为碗状,巢结构的2/3由苔藓构成;窝卵数为6～8枚,平均(6·92±0·92)枚(n=13);雌鸟单独孵卵,孵化期为(14·00±0·00)d(n=10);育雏由雌雄鸟共同承担,育雏期为(17·50±0·58)d(n=4)。杂色山雀繁殖成功率为50·95%,繁殖力为2·22。人为干扰是造成卵和雏鸟损失的主要原因,占总损失的74·19%。更多还原

【Abstract】 Reproductive success of Parus varius in both natural nests and nest-boxes was recorded in Baishilazi National Nature Reserve of Liaoning Province from March to July in 2004 to 2006.The birds nested in deciduous broad-leaved forest,artificial forest and conifer forest at elevation of 400 to 900 m above sea level from March to July.They built their nests in different cavities in a period of 15 days.The nest was bowl-like in shape,one-third of the whole nest was built by the material of lichen.Clutch size was 6-8 with an average of 6.92±0.92(n=13).Female incubated eggs and nestlings were hatched in 14.00±0.00 d(n=10).Both the male and female fed the nestlings for 17.50±0.58 d(n=4).The reproductive success of P.varius was 50.95% and reproductive capability index was 2.22.Human disturbances were the most negative influence factors that were responsible for 74.19% of the failure of breeding.更多还原
