中文摘要:
      2012~2013年4~7月,在陕西神木县红碱淖(N 39°04′21″~39**°04′43″,E 109°53′12″~109°53′40″)对白喉林莺(Sylvia curruca)的繁殖生态进行了研究。结果表明,白喉林莺4月末迁来繁殖,5月初开始营巢于油蒿、臭柏和沙棘灌丛中,巢口向上呈深杯状,由柳絮、枯枝和干草编织而成。对33个巢的参数进行了测量:巢外径9.62±0.227 cm,巢内径5.21±0.084 cm,巢深5.05±0.160 cm,巢高9.03±0.185 cm,巢距地面高度24.91±1.084 cm,约位于植被高度的1/3处。平均窝卵数4.83±0.081枚,卵重7.49±0.021 g,卵长径17.27±0.057 mm,卵短径为12.86±0.080 mm。孵化期为11~13 d,孵化率为93.7%,雏鸟出飞为91.4%。雏鸟的形态参数生长符合Logistic曲线方程拟合。植被高度、植被郁闭度和单株植被面积是制约白喉林莺巢址选择的主要因素,同时恶劣天气和人为干扰是影响繁殖成效的主要原因。
英文摘要:
      Breeding ecology of Lesser Whitethroat (Sylvia curruca) was studied in Hongjiannao (N 39°04′21″~39**°04′43″,E 109°53′12″~109°53′40″) of Shaanxi Province from April to July in 2012 and 2013. The results showed that the Lesser Whitethroat (Sylvia curruca) arrives at this breeding area in late April and nesting on branches of Artemisia ordosia, Sabina vulgaris and Hippophae rhamnoides in early May, the cup-shaped nests were upward and made of catkin, deadwood and hay. The nest parameters were measured in 33 of 35; external dimension of nest, internal dimension of nest, nest depth and nest height were 9.62±0.227 cm, 5.21±0.084 cm, 5.05±0.160 cm, 9.03±0.185 cm, respectively. The nest height above ground was 24.91±1.084 cm and located in lower part of vegetation (about 1/3). The mean clutch size was 4.83±0.081, The weight, length and breadth of eggs were 7.49±0.021 g, 17.27±0.057 mm and 12.86±0.080 mm, respectively. Incubation lasted for 11~13 d, Hatching and survival rate of Lesser Whitethroat were 93.7% and 91.4%. The morphological parameters of nestlings were suitable to fit to Logistic curves. The height, canopy and cover area of individual vegetation were the key factors for nest-sites selection, the foul weather and human disturbation were important factors to affect breeding success.
