摘要: 对分布于吉林白城地区草原生境中栗斑腹巫鸟的窝卵数、营巢成功率和繁殖成功率的初步研究结果表明,繁殖期栗斑腹巫鸟种群的平均窝卵数为5.09±0.58枚/巢;窝卵数与产卵期、出巢数与产卵期、窝卵数与卵大小之间呈负相关,产卵期与孵化率之间存在极显著的负相关关系,巢外径与窝卵数之间存在显著的正相关关系,巢的其余指标均与窝卵数呈正相关;平均孵化期为12±0.49d,孵化率为36.3%,繁殖成功率为11.11%;7日龄以上的雏鸟群体大小为2.56±1.53只,栗斑腹巫鸟的雏鸟存活率为27.69%.

Abstract: In this article,clutch size,nesting success and breeding success rate of Emberiza jankowskii living in grassland habitats in Baicheng Region of Jilin Province were studied from May to July in 1999. The results showed average clutch size was 5.09?0.58 eggs per nest. There was negative correlation between clutch size and initial laying date,brood quantity and initial laying date,clutch size and fresh egg weight. There was exceedingly negative correlation between initial laying date and incubated rate. There was exceedingly positive correlation between nest size and clutch size. There was positive correlation between other attributes of nest and clutch size. Average incubation period was 12?094 days, incubated rate was 36.3%,and breeding success rate was 11.11%. The population size of brood size above seven days was 2.56?1.53. Nestling survival rate was 27.69%.
