Abstract：
Due to rapid homogenization in habitat types as a result of urbanization, some urban birds adapt their nesting strategies to changes in local habitat characteristics. Bird nesting decisions might have been mainly linked to resource constraints and ensuring reproductive success. In this study, we examined patterns of nesting behavior by spotted doves (Spilopelia chinensis) in a rapidly urbanizing area of Nanchang, China using ArcGIS 10.8, satellite tracking, camera traps, and field survey. To explore the mechanisms underlying nesting behavior in urban habitats, we assessed the correlations between nest reuse and reproductive success, and between nest reuse and nest predation. From December 2018 to December 2021, a total of 302 breeding nests were surveyed. The results revealed that the nest reuse rate was 38.08% (n = 115). Nests closer to trunk, with lower nest position and higher large-scale urbanization score tended to have higher reuse rate. In addition, nests with the higher the nest height and percent of canopy cover, and the lower small-scale urbanization score were more likely to reproduce successfully, and the reused nests also reproduce more successfully. The reproductive success associated with nest reuse was significantly higher than that associated with new nests (χ 2 = 8.461, p = .004). High degree of urbanization promoted nest reuse of spotted doves (large-scale urbanization score, z = 2.094, p = .036), which apparently enhanced their reproductive success (nest reuse, z = 2.737, p = .006). In conclusion, a nest structure with good permeability is the material basis for the nest reuse in spotted dove, while the relatively low risk of predation in urban habitat and the scarcity of nest site resources due to urbanization increase the tendency of birds to reuse old nests, which is associated with their reproductive success and evolutionary fitness.
摘要：
由于城市化导致栖息地类型的快速同质化，一些城市鸟类根据当地栖息地特征的变化调整筑巢策略。鸟类筑巢决定可能主要与资源限制和确保繁殖成功有关。在这项研究中,我们研究了南昌快速城市化地区斑点鸽子（Spilopeliachinensis）的筑巢行为模式，中国使用ArcGIS10.8，卫星跟踪，相机陷阱,和实地调查。为了探索城市栖息地筑巢行为的潜在机制，我们评估了鸟巢重复使用和繁殖成功之间的相关性，在巢重用和巢捕食之间。从2018年12月到2021年12月，共调查了302个繁殖巢。结果表明，嵌套重用率为38.08%(n=115)。靠近树干的巢穴，较低的巢穴位置和较高的大规模城市化分数往往具有较高的重用率。此外,巢的高度和冠层覆盖率越高，较低的小规模城市化分数更有可能成功重现，重复使用的巢也更成功地繁殖。与窝重复使用相关的繁殖成功率显着高于与新窝相关的繁殖成功率（χ2=8.461，p=.004）。高度的城市化促进了斑鸽的巢再利用(大规模城市化得分，z=2.094，p=.036），这显然增强了它们的繁殖成功(巢的重复使用，z=2.737，p=.006）。总之,具有良好渗透性的巢结构是斑鸽巢再利用的物质基础，而城市栖息地捕食风险相对较低，城市化导致巢址资源稀缺，增加了鸟类再利用旧巢的趋势，这与他们的生殖成功和进化适应性有关。
