"Swedish power giant Vattenfall did a two-year, €3 million study of seabirds at
an offshore wind farm off Scotland – here’s what it found.
The aim of the 115-page study, which took place at Vattenfall’s 11-turbine
Aberdeen Offshore Wind Farm, aka the European Offshore Wind Deployment Center,
was:
…to improve our understanding of seabird flight behavior inside an offshore
wind farm. This should be achieved through collection of as detailed seabird
flight data as possible rather than through estimation of avoidance rates
for collision risk modeling per se.
Vattenfall, which is owned by the Swedish state, combined radar data with
cameras to identify the species of seabird and create a three-dimensional image
of birds’ flight patterns and how they avoid offshore wind turbines’ rotor
blades.
The movements of herring gulls, gannets, kittiwakes, and great black-backed
gulls were studied in detail from April to October, when bird activity is at
its height. (This study only looked at four bird species, but Vattenfall says
the model can and should be applied to more types of seabirds and to onshore
wind farms as well.)
The study’s findings: Not a single collision between a bird and a rotor blade
was recorded."
Via Kevin O'Brien, who wrote "So, as I expected that Republican bullshit that
we can’t have wind power because blades kill birds is just that: bullshit."
