摘　　要：2019年5—6月,在内蒙古扎鲁特旗对栗斑腹鹀(Emberiza jankowskii)的孵化行为进行了研究.结果表明:孵化期内成鸟的日离巢次数为(10.48±2.57)次(n=25),每次离巢持续时间介于1~90 min范围内,其中94.9%集中在1~30 min内,平均每次离巢持续时间为(16.33±2.18)min(n=276);坐巢时间为(47.90±59.12)min(n=299).与繁殖失败的巢相比,繁殖成功巢的成鸟离巢次数少但离巢时间长.From May to June 2019,a study was carried out on the incubation behavior of Jankowsk s Bunting at Jarud Banner in Inner Mongolia.According to the detection of 11 nests,the results showed that the birds took(10.48±2.57)times(n=25)of the recesses per day,and the duration of each departure was within the range of 1~90 min,of which 94.9%were concentrated in 1~30 min.Average recess time was(16.33±2.18)min(n=276)and the duration on-nest was(47.90±59.12)min(n=299).The study found that,compared with the failed birds,the successful took less and longer recesses.
