Fishers off Cornwall, in south-west England, have cut the accidental drowning of diving seabirds such as razorbills and guillemots by testing eye-decorated buoys and bird-shaped kites near their gillnets (vertical walls of netting hung under the surface), according to a two-year University of Exeter study in Conservation Letters. The devices lowered the chance of birds being caught by 59% and 71% respectively, and the work matters because an estimated 95,000 diving birds are caught in nets off European coasts each year. The research also found most Cornish bycatch happens in winter, which could help target the measures by season.
