| 中文摘要: |
| 灰头麦鸡（Vanellus cinereus）隶属鸻形目鸻科，在江西吉安地区是夏候鸟。2015年3~4月我们在井冈山大学校园内对灰头麦鸡的繁殖及孵卵节律进行了初步研究。结果显示，灰头麦鸡的窝卵数为4.0枚（n=4），卵鲜重平均为26.9 g，卵量度平均为：47.0 mm×34.2 mm。根据对4个巢的监测，灰头麦鸡在孵卵期的平均日离巢次数是5.6次，平均日离巢时间在86.6~95.2min之间，平均在巢率为87.5%（n=4）。研究发现，天气会影响鸟类的孵卵节律，相比阴天和雨天，晴天离巢次数和离巢时间最少。 |

| Vanellus cinereus, belonging to Charadriidae Charadriiformes, which is the summer resident in Ji'an, Jiangxi province. The breeding and the incubation rhythms were investigated in Jinggangshan University during March-April, 2015. The clutch size is 4.0, with eggs having the average volume index of 47.0×34.3 mm and weight of 26.9. According to the monitoring of the 4 nests, number of daily recess is 5.6, and average recess time is 86.6-95.2 min. The average nest constancy is 87.5% (n=4). The results showed the weather can affect the incubation rhythms. Numbers of daily recess and average recess time in sunny days were less than those in cloudy days and in rainy days. |
