骨顶鸡的繁殖行为

Breeding behavior of common coot(Fulica atra)

2008和2009年4—9月,对黑龙江省安邦河自然保护区以及龙凤湿地骨顶鸡繁殖种群进行了观察。结果表明:骨顶鸡繁殖季节会建造3种巢结构:炫耀台、产卵巢和育雏巢,雌雄共同参与筑巢及领域防卫活动;巢高和巢深随窝卵数增多而呈上升趋势;平均窝卵数为8.77±0.24(n=75)枚,窝卵数随繁殖时间推迟而呈减少趋势;骨顶鸡雌雄共同参与孵化,雌性平均每次孵化时间高于雄性;雌雄共同参与喂雏,雏鸟至亚体阶段才完全独立,之前需亲鸟饲喂;骨顶鸡是杂食性鸟类,食物以植物为主,但也摄取动物性食物。

An investigation was conducted on the breeding Fulica atra population in Anbanghe Nature Reserve and Longfeng wetland of Heilongjiang Province from April to September,2008 and 2009.The F.atra in breeding season built three kinds of nest structures,i.e.,display platform,egg nest,and brood nest.Both the female and the male participated in the construction of these structures,and protected their territory.The nest height and depth increased with clutch size,but the nest diameter didn＇t.The clutch size decreased with the delay of breeding time,with a mean value of 8.77±0.24（n=75）.Both the female and the male made incubation,and the female consumed more time in each incubation event.The female and the male nursed the nestlings together,and some of the young birds were fed by their parents until at sub-adult stage.F.atra was omnivorous.The food list was mainly made up of vegetations,but also contained some animals.
