Beware the giant googly eyes! Scientists deploy 'floating scarecrows' off the coast of Cornwall to deter seagulls

If you look out to sea and spot a giant set of eyes staring back at you, don't be alarmed. Scientists have deployed a 'floating scarecrow' off the coast of Cornwall.The floating scarecrow, also known as the Looming Eye Buoy (LEB), is designed to save seabirds from getting caught in fishing nets. 'The Looming Eye Buoy is essentially a rotating head with an eye, which gives the impression of an animated, or looming eye, which deters the birds from going near the fishing nets,' said Tom Hooper, senior fisheries scientist at Fishtek Marine. While this sounds rather comical, a study has revealed that the technique is actually very effective. Afer being deployed, the chances of guillemots and razorbills being caught in nets dropped by 59 per cent. If you look out to sea and spot a giant set of eyes staring back at you, don't be alarmed. Scientists have deployed a 'floating scarecrow' off the coast of Cornwall During a two–year trial, 10 Cornish fishermen had cameras fitted to their boats to monitor the effects of these methods on seabird bycatch levelsEach year, around 95,000 seabirds are incidentally caught and drown in nets around the coast of Europe. Known as 'bycatch', this is an issue that affects several species, including guillemots and razorbills. In their new study, researchers from the University of Exeter tested two methods to deter birds from these nets – LEBs, and 'scarybird' kites. As the name suggests, scarybird kites are kites shaped like predators. During a two–year trial, 10 Cornish fishermen had cameras fitted to their boats to monitor the effects of these methods on seabird bycatch levels. And the results revealed that both of these methods were highly effective. The chances of birds being caught were reduced by 59 per cent using LEBs and by 71 per cent using kites. 'This study provides some of the strongest evidence to date that simple, practical deterrents can substantially reduce seabird bycatch in gillnet fisheries,' said Tom Horton, lead author from the University of Exeter.'By also identifying when and where bycatch risk is highest, we now have a clear opportunity to target mitigation measures where they can deliver the greatest conservation benefit for vulnerable seabird populations and encourage sustainable fishing practices.' Earlier this year, scientists from the University of Exeter suggested sticking eyes on takeaways to keep pesky birds at bay Scientifically proven ways to deter seagulls Shout at themWear contrasting patterns such as zebra stripes or leopard printMaintain eye contact with any gulls that are starting to stray too closeEat underneath a parasol, umbrella, roof, narrowly–spaced bunting or even with your back against a wallNever leave a bag unzippedNever feed them for fun Stick googly eyes on your food Mr Hooper added: 'Any technology used at sea must be simple and robust, so working with fishermen means that we learned a great deal about how the devices were used and as a result we can refine and improve so that it fits their operational needs.'This isn't the first time scientists have turned to googly eyes to deter seabirds. Earlier this year, scientists from the University of Exeter suggested sticking eyes on takeaways to keep pesky birds at bay. In their study, the team stuck googly eyes on takeaway food boxes to test whether it would affect their appeal to hungry gulls. Amazingly, they found that the gulls were put off by the eyes, and were slower to approach and less likely to peck at the boxes.'Many animals – both wild and domesticated – are very aware of eyes, which can indicate the presence of a predator or be used to communicate intent,' explained lead author, Dr Laura Kelley, in an article for The Conversation. 'Direct eye contact often conveys aggression, while looking away indicates a lack of threat.'Animals generally respond defensively when they see eyes staring at them.'
