小白腰雨燕 Little Swift or House Swift (Apus affinis)

雨燕目 > 雨燕科 > 雨燕属 APODIFORMES > Apodidae > Apus affinis

描述:中等体型(15厘米)的偏黑色雨燕。喉及腰白色,尾为凹型非叉型。与体型较大的白腰雨燕区别在于色彩较深,喉及腰更白,尾部几乎为平切。

虹膜-深褐;嘴-黑色;脚-黑褐。

叫声:非常响。飞行时发出响亮而高亢的快速重复颤音der-der-der-dit-derdiddiddo...o,尤其是在傍晚夜宿前。

分布范围:非洲、中东、印度、喜马拉雅山脉、中国南部、日本、东南亚、菲律宾、苏拉威西及大巽他群岛。

分布状况:常见留鸟及季节性候鸟,上至海拔1500米。亚种nipalensis繁殖于中国南部的大部地区及海南岛;亚种kuntzi为台湾留鸟。

习性:成大群活动,在开阔地的上空捕食,飞行平稳。营巢于屋檐下、悬崖或洞穴口。

注:东亚的亚种有时作为独立种A. nipalensis (参见Chantler & Driessens,1995;Viney et al., 1994)。中国所有标本过去均为南方亚种subfurcatus (见郑作新, 1994)。

Little Swifts breed around habitation and cliffs from Africa northeastwards through southern India and Sri Lanka. Unlike the more northerly Common Swift, many birds are resident, but some populations are migratory, and winter further south than their breeding areas. They wander widely on migration, and are seen as rare vagrants in much of Europe and Asia.
