Mass birds die, now in Sweden
Veterinary doctors after studying the dead birds sample said, "difficulties in finding food and possible shock from the fireworks could be responsible, led to the stressed birds either died from the stress or being ran over by vehicles."
Mass bird deaths are not uncommon. More than 5000 dead birds fell out of the skies over Beebe state in Arkansa on New Year's Eve. In Arkansas last year 85,000 fish were found dead in an anonymous way.
