Swedish power giant Vattenfall did a two-year, \u20ac3 million study of seabirds at an offshore wind farm off Scotland \u2013 here\u2019s what it found.<\/p>\n

<\/p>\n

The aim of the 115-page study<\/a>, which took place at Vattenfall\u2019s 11-turbine Aberdeen Offshore Wind Farm<\/a>, aka the European Offshore Wind Deployment Center, was: <\/p>\n

\n

\u2026to 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.<\/p>\n<\/blockquote>\n

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\u2019 flight patterns and how they avoid offshore wind turbines\u2019 rotor blades.<\/p>\n

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.\u00a0(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.)\u00a0<\/p>\n

The study\u2019s findings: Not a single collision between a bird and a rotor blade was recorded.<\/p>\n

Vattenfall says that the herring gulls and kittiwakes showed horizontal avoidance further away from rotor blades, 90-110 meters (295-361 feet) and 140-160 meters (459-525 feet), respectively, while the gannets and great black-backed gulls only exhibited avoidance behavior at 40 and 50 meters (131 and 164 feet) from the tips of rotor blades.<\/p>\n

And if you just muttered under your breath, \u201cWell, they would<\/em> say that, wouldn\u2019t they?\u201d Vattenfall says it\u2019s got video evidence to back up its study\u2019s findings \u2013 ten thousand videos of birds flying around Aberdeen Offshore Wind Farm, in fact.<\/p>\n

Henrik Skov, who led the project, said:<\/p>\n

\n

This is the first time that any kind of bird species has been studied this closely and in detail at an offshore wind farm. And these birds are really good at avoiding the turbines. Now we need studies on more varieties.<\/p>\n<\/blockquote>\n

He added that surveys on bird behavior are part of an overall effort to avoid building wind farms in flight corridors.<\/p>\n
