Ecosystem overviews

Greater North Sea Ecoregion

Ecosystem components: Seabirds

The ecoregion is an important feeding area for many seabird populations preying on fish and invertebrates. More than 20 species of seabird breed on the coasts of the ecoregion, with numbers generally increasing until 2000, followed by a decline. The Greater North Sea is an important wintering area for migratory birds from the north and east. Generally, the number of immigrant seabirds has declined in past years, likely due to milder winters, suggesting that the flocks that used to reach the region in winter remain now closer to their breeding grounds.

The main threats come from climate change, fishing (including bird bycatch and competition for prey items), disturbance from shipping, and detrimental interactions with offshore renewables (including collisions with wind turbine blades). ​​
