During the winter season, an extensive population of crows (predominantly the carrion crow ) seek refuge in Beijing's urban landscapes for roosting, subsequently generating noise and droppings that adversely affect the quality of life of residents. This study elucidates the selection criteria employed by crows in Beijing's urban areas for roosting sites. Drawing upon historical records and the outcomes of our survey, we observed a remarkable consistency in the selection of roosting locations by crows over time, with the same locations being preferentially chosen across different years. We also conducted a quantitative analysis of the habitat characteristics associated with the crow roosting sites. We discovered that crows demonstrate a preference for roosting sites situated in proximity to human structures, particularly towering buildings, which are often adjacent to broad roads. By understanding the factors that influence the selection of roosting sites by crows, policy-makers and urban planners can devise targeted interventions aimed at mitigating conflicts between humans and crows.
在冬季，大量乌鸦（主要是小嘴乌鸦）在北京的城市景观中寻找栖息之所，随后产生的噪音和粪便对居民的生活质量产生了不利影响。本研究阐明了北京城区乌鸦选择栖息地点的标准。根据历史记录和我们的调查结果，我们观察到随着时间推移，乌鸦在选择栖息地点方面具有显著的一致性，不同年份都优先选择相同的地点。我们还对与乌鸦栖息地点相关的栖息地特征进行了定量分析。我们发现，乌鸦偏好栖息在靠近人类建筑的地方，特别是高楼大厦，这些地方通常毗邻宽阔的道路。通过了解影响乌鸦选择栖息地点的因素，政策制定者和城市规划者可以制定有针对性的干预措施，以减轻人类与乌鸦之间的冲突。
