| We have been the first to investigate whether
long-lived geese and ducks can detect and avoid
a large offshore wind farm by tracking their
diurnal migration patterns with radar. We found
that the percentage of flocks entering the wind
farm area decreased significantly (by a factor
4.5) from pre-construction to initial operation.
At night, migrating flocks were more prone to
enter the wind farm but counteracted the higher
risk of collision in the dark by increasing their
distance from individual turbines and flying in
the corridors between turbines. Overall, less
than 1% of the ducks and geese migrated close
enough to the turbines to be at any risk of
collision. | |
