Adding a pair of google eyes to a buoy can help deter seabirds from getting tangled in fishing gear. Gillnets particularly damage 400,000 seabirds a year. The birds can smell the fish inside the nets from miles away. But when they reach the net, they can get tangled in it and drown. In a recent study, researchers tested out if putting a pair of looming eyes on a pole attached to a buoy would deter birds from going to an area. The idea was that if it worked, the devices could be put up in gillnet fisheries. The eyes worked. In Küdema Bay in Estonia, the long-tailed ducks (Clangula hyemalis) stayed farther away from buoys with eyes on them compared to traditional buoys.
