Many hirundine (swallows and martins) species are declining throughout their ranges. The Common House Martin Delichon urbicum is a migratory hirundine that breeds throughout Europe but has shown recent declines in some parts of the UK, particularly in the south. We conducted a large‐scale citizen science survey to assess how the breeding performance of House Martins, measured by the number of attempted broods and nest success, is influenced by nest‐specific, landscape and weather factors. Pairs in eastern parts of the UK started breeding earlier than those in the west, and breeding performance was higher in eastern regions. There was no effect of latitude on either aspect of breeding performance, so our measures of breeding performance alone do not help to explain differences in population trends across the UK. The probability of attempting multiple broods and producing successful nests was higher in previously used nests than in newly built nests, and in artificial nests than in natural nests. Nests built on plastic soffits of buildings were less likely to be multi‐brooded and less likely to be successful compared with other materials. Suggested conservation measures therefore include discouraging the removal of old nests and encouraging the installation of artificial nests, particularly on buildings with plastic soffits. This study provides comprehensive insight into the breeding biology of House Martins, and although our findings do not show conclusively that breeding performance is the sole driver of population trends, they go some way to explain declines in House Martins and ultimately provide information that may help conserve this species.

使用公民科学评估普通房马丁·德利雄乌比库姆繁殖性能的驱动因素

许多平日(燕子和马丁)物种在其整个范围内都在下降。普通房马丁·德利雄·乌比库姆是一种在欧洲各地繁殖的候鸟,在英国的某些地区,特别是南部地区,最近的数量有所下降。我们进行了一项大规模的公民科学调查,以评估家禽的繁殖性能(通过尝试的育雏次数和成功成巢的方式来衡量)如何受特定巢穴,景观和天气因素的影响。英国东部的配对开始繁殖的时间要早​​于西方的配对,并且东部地区的繁殖表现更高。纬度对育种表现的任何方面都没有影响,因此仅凭育种表现的测量方法就无法解释整个英国人口趋势的差异。在以前使用过的巢中,尝试多个育雏并产生成功的巢的可能性比在新建巢中高,与人工巢相比,自然巢更是如此。与其他材料相比,在建筑物的塑料拱腹上建巢的可能性较小,也不太可能成功。因此,建议的养护措施包括不鼓励拆除旧巢,并鼓励安装人工巢,特别是在带有塑料拱腹的建筑物上。这项研究提供了关于豪斯马丁斯育种生物学的全面见解,尽管我们的发现并不能最终表明育种性能是种群趋势的唯一驱动因素,但它们以某种方式解释了豪斯马丁斯的衰落并最终提供了有助于保护的信息。这个物种。与其他材料相比,在建筑物的塑料拱腹上建巢的可能性较小,也不太可能成功。因此,建议的养护措施包括不鼓励拆除旧巢,并鼓励安装人工巢,特别是在带有塑料拱腹的建筑物上。这项研究提供了关于豪斯马丁斯育种生物学的全面见解,尽管我们的发现并不能最终表明育种性能是种群趋势的唯一驱动因素,但它们以某种方式解释了豪斯马丁斯的衰落并最终提供了有助于保护的信息。这个物种。与其他材料相比,在建筑物的塑料拱腹上建巢的可能性较小,也不太可能成功。因此,建议的养护措施包括不鼓励拆除旧巢,并鼓励安装人工巢,特别是在带有塑料拱腹的建筑物上。这项研究提供了关于豪斯马丁斯育种生物学的全面见解,尽管我们的发现并不能最终表明育种性能是种群趋势的唯一驱动因素,但它们以某种方式解释了豪斯马丁斯的衰落并最终提供了有助于保护的信息。这个物种。特别是在带有塑料拱腹的建筑物上。这项研究提供了关于豪斯马丁斯育种生物学的全面见解,尽管我们的发现并不能最终表明育种性能是种群趋势的唯一驱动因素,但它们以某种方式解释了豪斯马丁斯的衰落并最终提供了有助于保护的信息。这个物种。特别是在带有塑料拱腹的建筑物上。这项研究提供了关于豪斯马丁斯育种生物学的全面见解,尽管我们的发现并不能最终表明育种性能是种群趋势的唯一驱动因素,但它们以某种方式解释了豪斯马丁斯的衰落并最终提供了有助于保护的信息。这个物种。
