Abstract The matching of breeding with the food peak is one of the most important factors affecting the reproductive success in birds. Weather is known to affect the timing of breeding of many bird species. In arid lands, rainfall is usually the factor that triggers the onset of reproduction, since it commonly anticipates the peak of food through its influence on the vegetation development. In this study we used a granivorous finch (European greenfinch Chloris chloris) as a model to assess the influence of rainfall and temperature on the onset and performance of breeding. The study was carried out in fruit orchards in Guelma state (Northeastern Algeria) in 2013 and 2014. The comparison of breeding parameters between the two years showed that greenfinches delayed their breeding in the year that the rains fell later and were less abundant, produced smaller broods and had lower fledgling rate. Clutch size decreased with the season progress only this year. We discuss our results in the context of the influence of weather on bird reproduction in arid lands, while providing novel data on a farmland species from a region with little ornithological information.

在阿尔及利亚果园筑巢的绿翅雀在最干旱的两年里推迟了它们的繁殖并产生了更少的雏鸟

摘要 繁殖与食峰的匹配是影响鸟类繁殖成功的最重要因素之一。众所周知，天气会影响许多鸟类的繁殖时间。在干旱地区，降雨通常是触发繁殖开始的因素，因为它通常通过对植被发育的影响来预测食物高峰。在这项研究中，我们使用食谷雀科 (European greenfinch Chloris chloris) 作为模型来评估降雨和温度对繁殖开始和表现的影响。该研究于 2013 年和 2014 年在圭尔马州（阿尔及利亚东北部）的果园进行。 两年间繁殖参数的比较表明，绿翅雀在降雨较晚且较少的年份推迟了繁殖，产生较小的育雏和较低的雏鸟率。离合器尺寸仅在今年随着季节的进展而减少。我们在天气对干旱地区鸟类繁殖的影响的背景下讨论了我们的结果，同时提供了来自几乎没有鸟类信息的地区的农田物种的新数据。
