A large number of birds were found dead in Falkoping, Sweden, Tuesday night and Wednesday morning.
Autopsies on five birds were completed by the Swedish National Veterinary Institute. Their findings were no illness, no external signs of damage or blows of any kind and no infection. However, the birds showed signs of internal bleeding, which ultimately killed them.
In similar cases, Arkansas had thousands of red-winged blackbirds and starlings fall from the sky on New Year’s Eve in the small town of Beebe.
Monday morning, at least 500 birds fell dead in Labarre, Louisiana, showing the same symptoms. The birds dying there were also starlings, red-winged blackbirds and sparrows.
