It appears that some marine mammals are certainly welcoming the presence of offshore wind farms.
Satellite tags on grey and harbor seals reveal that these apex predators are frequenting two offshore wind farms in the North Sea to forage for prey. According to a study recently published in Current Biology, 11 seals showed evidence of foraging at the Alpha Ventus wind farm off Germany and the Sheringham Shoal wind farm off the United Kingdom, moving in a grid-like pattern as they swam from turbine to turbine.
