高黎贡山白尾梢虹雉繁殖生态观察

2002-2004年连续3个春季在高黎贡山自然保护区对白尾梢虹雉(Lophophorus sclateri)的繁殖习性进行了观察,对白尾梢虹雉的巢、卵和雏鸟进行了详细描述.在高黎贡山南段,白尾梢虹雉的产卵孵化始于3月底,止于5月初,窝卵数为2～3枚,孵卵期为28 d.窝卵数低、适宜巢址缺乏有可能是白尾梢虹雉种群增长缓慢...

The Breeding Behavior of the Sclater's Monal (Lophophorus sclateri)at Mt.Gaoligong

We conducted field studies on the breeding behavior of Sclater’s Monal(Lophophorus sclateri) on Mt Gaoligong in spring(March-May) at the year of 2002 to 2004.The single nest site found locates on a ledge(3.8 m) on the side of a large boulder(6.3 m).Egg-laying began in late March,incubation in early April,and chicks hatched in early May.Clutch size varied between 2 and 3 eggs(n = 2) and the laying interval between eggs was 2 days(n = 1).The eggs are cream-coloured,have fine reddish brown spots and average 85.8 g(n = 5).The incubation period is 28 days(n = 2) and chicks average 57.3 g(n = 3) at hatch.All of the eggs were fertile and hatched successfully.The single nest site that we found was used for at least two years,possibly three,suggesting that nest sites might be a limiting factor for this population.
