风能开发对许多鸟类具有复杂的生态后果。以往对鸟类类群的环境影响评价主要集中在风电场对鸟类的直接和间接影响，如碰撞死亡率、飞行变化和栖息地迁移等。它们对水鸟行为的影响研究较少，尤其是觅食行为，觅食行为决定了它们的能量收支，从而决定了它们的繁殖和生存。在这项研究中，我们研究了2019年6月至10月风电场和周围景观对小白鹭（Egretta garzetta）丰度和能量预算相关行为的影响，小白鹭是中国东部沿海风电场附近的主要居住水鸟物种。记录了白鹭的休息、运动和觅食三个行为类别，以及站立等待、慢速行走和快速行走三个觅食亚类别。我们还测量了每个样方内到风电场的距离和五个景观变量（水产养殖池塘边缘、沟渠、沼泽草地、沼泽开阔水域和河流）。小白鹭的丰度与养殖池塘边缘和湿地开放水域分别呈正相关和负相关，但与风电场距离的远近对小白鹭的丰度无显著影响。与风电场的距离与站立等待觅食呈正相关。此外，河流与运动呈负相关。沼泽开阔水域与步行缓慢觅食呈负相关。因此，崇明东滩小白鹭的丰度没有受到风电场的影响，尽管风电场导致它们的一些行为发生了变化。总的来说，这个风电场对小白鹭的影响是有限的。我们建议以白鹭为主的养殖池塘作为沿海风电场开发的替代方案。我们还强调了水鸟的行为评价作为风电场开发环境影响评价的补充技术。
Wind energy development has complex ecological consequences for many bird species. Previous environmental impact assessments (EIAs) for avian taxa mainly focused on the direct and indirect impacts of wind farm, such as collision mortality, flight changes, and habitat displacement. Their impact on waterbird behavior is less studied, especially foraging behaviors, which determine their energy budget and, thus, their reproduction and survival. In this study, we examined the effect of wind farms and the surrounding landscape on the abundance and energy budget-related behaviors of little egrets (Egretta garzetta), a dominant resident waterbird species near wind farms along the East China coast, from June to October 2019. Three egret behavioral categories were recorded, i.e., rest, locomotion, and foraging, and three foraging subcategories, i.e., stand-and-wait, walk slowly, and walk quickly. We also measured the distance to the wind farm and five landscape variables (aquaculture pond edge, ditch, marsh grassland, marsh open water, and river) within each quadrat. We found no significant effect of the distance to the wind farm on the abundance of little egrets, although their abundance was positively and negatively related to the aquaculture pond edge and marsh open water, respectively. The distance to the wind farm was positively correlated with stand-and-wait foraging. In addition, the river was negatively correlated with locomotion. Marsh open water was negatively correlated with walk slowly foraging. Therefore, the abundance of little egrets in Chongming Dongtan was not affected by the wind farm, although the wind farm resulted in changes to some of their behavior. Overall, the effect of this wind farm on little egrets was limited. We suggest aquaculture ponds mainly inhabited by egrets as alternatives for coastal wind farm development. We also highlight the behavioral evaluation of waterbirds as a complementary technique for EIAs of wind farm developments.
