Seabird monitoring at offshore wind farms in the Belgian part of the North Sea: Updated results for the Bligh Bank & first results for the Thorntonbank

Since 2005, the Research Institute for Nature and Forest (INBO) performs monthly BACI-designed surveys to study seabird displacement following the construction of offshore wind farms in the Belgian part of the North Sea. For the first time since its completion in 2013 we report our findings for the C-Power wind farm at the Thorntonbank, and we also give an update of the results for the Bligh Bank wind farm after five years of post-impact monitoring. Compared to earlier reports and publications, we introduced some improvements in our modelling strategy.
