SummaryConservation measures providing food-rich habitats through agri-environment schemes (AES) have the potential to affect the demography and local abundance of species limited by food availability. The European Turtle Dove Streptopelia turtur is one of Europe’s fastest declining birds, with breeding season dietary changes coincident with a reduction in reproductive output suggesting food limitation during breeding. In this study we provided seed-rich habitats at six intervention sites over a 4-year period and tested for impacts of the intervention on breeding success, ranging behaviour and the local abundance of territorial turtle doves. Nesting success and chick biometrics were unrelated to the local availability of seed-rich habitat or to the proximity of intervention plots. Nestling weight was higher close to human habitation consistent with an influence of anthropogenic supplementary food provision. Small home ranges were associated with a high proportion of non-farmed habitats, while large home ranges were more likely to contain seed-rich habitat suggesting that breeding doves were willing to travel further to utilize such habitat where available. Extensively managed grassland and intervention plot fields were selected by foraging turtle doves. A slower temporal decline in the abundance of breeding males on intervention sites probably reflects enhanced habitat suitability during territory settlement. Refining techniques to deliver sources of sown, natural, and supplementary seed that are plentiful, accessible, and parasite-free is likely to be crucial for the conservation of turtle doves.

种子丰富的栖息地提供对欧洲斑鸠 Streptopelia turtur 领土密度、栖息地和繁殖性能的影响

摘要通过农业环境计划 (AES) 提供食物丰富的栖息地的保护措施有可能影响受食物供应限制的物种的人口统计和当地丰度。欧洲斑鸠链球菌是欧洲下降最快的鸟类之一，繁殖季节的饮食变化与繁殖产量的减少同时发生，表明繁殖期间的食物限制。在这项研究中，我们在 4 年的时间里在六个干预地点提供了富含种子的栖息地，并测试了干预对繁殖成功、测距行为和当地斑鸠数量的影响。筑巢成功和雏鸡生物特征与当地是否有丰富的种子栖息地或干预地块的接近程度无关。靠近人类居住地的雏鸟重量较高，这与人为补充食物供应的影响一致。小型家庭范围与高比例的非农业栖息地有关，而大范围的栖息地更可能包含富含种子的栖息地，这表明繁殖鸽子愿意进一步旅行以利用这些可用的栖息地。通过觅食斑鸠选择粗放管理的草地和干预地块。干预地点繁殖雄性数量的较慢时间下降可能反映了领土定居期间栖息地适宜性的增强。精炼技术以提供丰富、可获取且无寄生虫的播种、天然和补充种子来源，对于保护斑鸠可能至关重要。干预地点繁殖雄性数量的较慢时间下降可能反映了领土定居期间栖息地适宜性的增强。精炼技术以提供丰富、可获取且无寄生虫的播种、天然和补充种子来源，对于保护斑鸠可能至关重要。干预地点繁殖雄性数量的较慢时间下降可能反映了领土定居期间栖息地适宜性的增强。精炼技术以提供丰富、可获取且无寄生虫的播种、天然和补充种子来源，对于保护斑鸠可能至关重要。
