山地次生林花尾榛鸡的繁殖

The Breeding of Bonasa Bonasia in Secondary-forest

作者在2002年和2003年2个繁殖期对吉林省左家次生林中花尾榛鸡(Bonasabonasia)的繁殖生态进行了研究.结果表明:花尾榛鸡营巢期在5月上旬,巢简陋但隐蔽,多处于倒木或倾斜度很大的树木之下,也有筑于灌丛中的.产卵多在5月上、中旬,窝卵数多为8～12枚,平均卵重15.65g±1.84(n=30),卵径38.4×28.02(n=30),雌鸟孵卵,孵化期为22.5±1.28天(n=5),孵化率为85.8%.

The breeding ecology of bonasa bonasia in secondary-forest was studied in Jilin Zuojia during the two breeding seasons in 2002 and 2003. The results show that: nest is simple and crude but concealing,and most of the nests are under the trees which fall down or the grediend of the trees is large, and some nests are also builded in the brush.Hatching is in the first and middle ten days of may.Clutch size varys between 8~12,average weight of egg is 15.65±1.84(n=30).The diameter of an egg is 38.4×28.02(n=30).The female hatch.The incubation period is 22.5±1.28 day(n=5),and the successful rate of breeding is 85.8%.
