摘　　要：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的重要因素。We conducted field studies on the breeding behavior of Sclater＇ s Monal（Lophophorus sclateri） on M t 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.
