MINIATURE “bird backpacks” or tiny tags on tail feathers could help reveal how seabirds move around Scotland’s offshore wind farms, and help to protect the birds.
The ideas are among responses to a challenge from the Offshore Renewable Energy (ORE) Catapult, the UK’s research centre for wind, wave and tidal energy, after offshore wind farm firms asked for more reliable tags to monitor seabirds.
The firms are under pressure to ensure their turbines do not impact on seabird movements and behaviour.

The tags must add no more than three per cent to the bird’s weight, have a battery that lasts a year, withstand attacks, and have quick-release mechanism to stop snagging.
Ideas include a bird backpack with a solar-powered GPS system, and tags which clip on to the feathers.
Four companies are now working to test devices before deployment around wind farms in the Moray Firth. The successful firm’s device will first be used on greater black-backed gulls. Vicky Coy from ORE Catapult said: “Developing a tag that withstands a bird’s natural behaviour is key to developing a greater understanding of their movements. It’s more difficult than it sounds.”
Catarina Rei from EDP Renewables, which is developing Moray East wind farm, said: “We’ll be able to gain a greater insight into bird and coastal species behaviour, which will better inform the planning, consenting and operational stage of an offshore wind farm development.”
Why are you making commenting on The National only available to subscribers?
We know there are thousands of National readers who want to debate, argue and go back and forth in the comments section of our stories. We’ve got the most informed readers in Scotland, asking each other the big questions about the future of our country.
Unfortunately, though, these important debates are being spoiled by a vocal minority of trolls who aren’t really interested in the issues, try to derail the conversations, register under fake names, and post vile abuse.
So that’s why we’ve decided to make the ability to comment only available to our paying subscribers. That way, all the trolls who post abuse on our website will have to pay if they want to join the debate – and risk a permanent ban from the account that they subscribe with.
The conversation will go back to what it should be about – people who care passionately about the issues, but disagree constructively on what we should do about them. Let’s get that debate started!
