Swedish scientists make many assumptions about this mass die-off. " It is likely that these birds are afraid of fireworks and landed on the road but cannot fly because of the stress and the car rolled, " The Local quoted Swedish veterinary doctor Robert ter Horst as saying.

Bird researcher Anders Wirdheim said that this phenomenon was surprising. " Unusual. This might be a gray crow crow. They often live in large flocks in the winter. If disturbed, they will stress and die ," he said.

The Swedish National Veterinary Institute will test for bacteria, including swine flu tests, to find the cause of the mass death, AFP said.

This phenomenon happened after about 5,000 bird carcasses were found in Arkansas and 500 fell to Louisiana, USA, in the past few days.
