摘　　要：筑巢是鸟类繁殖过程的重要阶段,为繁殖成功提供重要保障。为了解新定殖种群的繁殖策略,本文以在广西沿海留居繁殖的黑翅长脚鹬作为研究对象,对其巢址选择进行研究。结果表明:1)2022年3-6月,共记录到巢37个,巢外径(18.806±3.728)cm,巢内径(9.759±1.365)cm,巢高(3.006±1.561)cm;2)主成分分析表明,影响巢址选择的生态因子为植被因子、社交因子、隐蔽度因子、巢材因子、干扰因子;3)通过巢区与对照区的对比分析发现,黑翅长脚鹬偏好于草本均高较大(14.844±1.549)cm、距大路距离更远(357.108±71.118)m、隐蔽度更高(1.622±0.2063)的地点筑巢;4)通过成功巢与失败巢的对比分析表明,在距大路距离、觅食地明水面积以及隐蔽度等生态因子方面差异显著。Nesting during the breeding period is an important stage in the life history of birds and is crucial to successful breeding.Since 1997,more and more individuals of Black-winged Stilt have been found breeding on the coast of Guangxi,China.To understand the breeding strategy of this new colonization population,this shorebird was chosen as a model to study its nest site selection.From March to June,2022,a total of 37 nests were found.The outer,inner diameter and nest height were(18.806±3.728)cm,(9.759±1.365)cm and(3.006±1.561)cm respectively.Principal component analysis showed that the nest variables of Stilts were related to vegetation,social,concealment,nest material and disturbance.Higher height of herb(14.844±1.549)cm,far from the road(357.108±71.118)m and certain concealment level(1.622±0.2063)played the key roles in nest-site selection.Results of the comparison between successful and unsuccessful nests showed that the distance to the road,open water area of the foraging ground and concealment are significantly different.
