Knowledge of the factors influencing variation of nest abundance in cities is a major topic in urban ecology with important management and planning implications. In the present study, we aimed to investigate this issue with regards to white stork (WS) (Ciconia ciconia) in the capital of Morocco, Rabat. Here, we used data on a series of topographic, anthropogenic, and landscape variables to identify best predictors causing variation in the WS nest abundance by means of generalized linear models. Results revealed an increase in nest abundances with a weaker length of roads and greater non-built-up areas. Therefore, the less urbanized the areas of the city of Rabat are, the more attractive for nest establishment by storks they are. This information is of use to the Rabat urban environmental managers in order not only to (1) maintain this Ciconiidae species at manageable levels but also to (2) suitably manage this city taking into account the needs of storks. Reproducing this study in other Mediterranean urban areas would be relevant to find out if variation in nest abundances of this species depends on the same factors as those in Rabat.

寻求城市化程度最低的景观：地中海首都城市白鹳巢的丰度变化

了解影响城市燕窝数量变化的因素是城市生态学的一个重要主题，具有重要的管理和规划意义。在本研究中，我们旨在调查有关白鹳（WS）（Ciconia ciconia）在摩洛哥首都拉巴特。在这里，我们使用了一系列地形，人为和景观变量的数据，以通过广义线性模型确定导致WS巢丰度发生变化的最佳预测变量。结果表明，筑巢丰度增加，道路长度变短，未建成区域增加。因此，拉巴特市的城市化程度越低，它们对鹳巢筑巢的吸引力就越大。该信息对拉巴特的城市环境管理人员有用，不仅是为了（1）将该Ciconiidae物种维持在可管理的水平，而且（2）考虑到鹳的需要对这个城市进行适当的管理。
