摘要

虽然南财政Lanius collaris是纳米比亚南部常见的物种，但我们只发现了18个猎物的刺具。我们根据刺穿的种类、刺穿的地点、离地高度和一年中的时间来讨论这些问题。我们认为，观测结果较少是由于研究期间(2017年7月至2022年6月)降雨量低于平均水平，因此食物稀缺和消耗，并且刺穿事件很少发生。

Prey items of Southern Fiscal Lanius collaris in southern Namibia

Although Southern Fiscals Lanius collaris are a common species in southern Namibia, we found only 18 impalements of prey items. We discuss these in relation to the species impaled, the site of impalement, the height above ground and the time of the year. We suggest that the small number of observations was due to the fact that the study period (July 2017 to June 2022) had below average rainfall, that food was therefore scarce and consumed, and that impalements events were rare.
