1998年4月中旬~7月中旬,对分布于新疆木垒的波斑鸨(Chlamydotis undulata macqueenii)种群的营巢成功率进行了初步考察与研究。考察中共发现16个巢、25窝幼雏。每巢产卵3~6枚,卵鲜重(64.7±5.8)g,卵径为60.9 mm×43.9 mm。产卵有两个高峰期,表明雌鸟第 1次繁殖失败后可再次产卵。第1产卵期的巢卵数为(4.1±0.8)枚,第2产卵期的巢卵数为(3.5±0.6)枚。雌鸟营巢成功率为77.5%~87.5%,卵的孵化率为83.6%。每窝内从破壳到具备飞行能力的幼雏数基本不变,表明繁殖雌鸟大都能将幼雏全部抚育到可以飞行的年龄。
A Preliminary Study on the Nesting Success in Houbara Bustard (Chlamydotis undulata macqueenii) Population in Mulei Xinjiang
Nesting success of Houbara Bustard (Chlamydotis undulata macqueenii) was studied in Mulei,Xinjiang from April to June,1998. A total of 16 nests and 25 broods were found. A bimodal distribution of laying dates suggested the existence of a replacement clutch. 3 to 6 eggs were laid with the fresh weight of (64.7±5.8)g and the size of 60.9 mm×43.9 mm.The clutch size was (4.1±0.8) for the first clutch cohort and (3.5±0.6) for the second clutch cohort. The nesting success was 87.5%. The hatchability was 83.6%. Brood size keep the same within broods between hatching and fledging. This suggested that some females were very good at bringing their chicks to fledging.
