What to know about Wildlife Deterrence Technology

Researchers from the Technical University of Denmark tested the Looming-Eye Buoy (LEB), a device designed to deter fish-eating seabirds from pound nets. The study found that while the device initially reduced the number of birds, the effect disappeared after approximately one month as the birds learned the devices were not threats.

What happened

May 27, 2026 report Fake predator eyes scare off seabirds until they learn they're not real Paul Arnold Author Lisa Lock Scientific Editor Robert Egan Associate Editor In Danish fisheries, fish-eating seabirds are a menace.

Why it matters

They often swoop down and feed on fish trapped in nets, which can hit profits and also sometimes lead to the accidental death of the birds.

Common ground

So scientists deployed an unusual-looking, non-lethal method to deter them.
