AUTOPSIES showed the flock of birds found dead on the streets of Falkoping, in central Sweden, died of acute blunt force and not any kind of infection or disease, the Swedish news website The Local reported Thursday. The Local said five of the dead jackdaws – a European bird of the crow family – were autopsied by the national Veterinary Institute (SVA), where zoologist Marianne Elvander said they died of severe internal bleeding.
The Swedish bird deaths marked the third such mysterious incident in less than a week.
Some 500 dead birds were found next to a highway northwest of Baton Rouge, Louisiana, US on Monday, littering a quarter-mile stretch of road. The carcasses included starlings and blackbirds, the latter the same as the nearly 5,000 birds that plunged to the ground in Beebe, Arkansas, on New Year's Eve.
