通过事前-事后控制-撞击设计的基于船舶的海鸟调查，研究了2010年比利时布莱海岸安装海上风力发电场后发生的海鸟流离失所现象。结果表明，北方灵芝(Morus Basanus)、海燕(Uria Aalge)和斑嘴鸟(Alca Torda)避开了风电场，分别以85%、71%和%的数量减少。小黑嘴鸥(Larus Fuscus)和鲱鸥(Larus Argentatus)被吸引到风电场，数量分别增加了5.3和9.5倍。其他种类的海鸥也被发现经常出现在涡轮机建造的区域，最著名的是普通海鸥(Larus Canus)、黑腿海鸥(Rissa Tridactyla)和大黑背海鸥(Larus Marinus)。所观察到的吸引效应背后的生态诱因仍然鲜为人知，但除了栖息可能性的增加外，海上风电场提供了更多的觅食机会是有可能的。重要的是，海鸟被海上风电场吸引意味着碰撞风险增加。
Through before–after control-impact designed ship-based seabird surveys, seabird displacement occurring after the installation of an offshore wind farm at the Belgian Bligh Bank in 2010 was studied. Results demonstrate that northern gannet (Morus bassanus), common guillemot (Uria aalge) and razorbill (Alca torda) avoided the wind farm area, and decreased in abundance with 85, 71 and 64%, respectively. Lesser black-backed gull (Larus fuscus) and herring gull (Larus argentatus) were attracted to the wind farm, and their numbers increased by a factor 5.3 and 9.5. Other gull species too were found to frequent the turbine-built area, most notably common gull (Larus canus), black-legged kittiwake (Rissa tridactyla) and great black-backed gull (Larus marinus). The ecological incentives behind the observed attraction effects are still poorly understood, but on top of the increase in roosting possibilities it is plausible that offshore wind farms offer enhanced feeding opportunities. Importantly, attraction of seabirds to offshore wind farms implies an increased collision risk.
