Hier ein Bericht aus Schweden über die evenuelle Todesursache.
"In Sweden, the 50-100 dead jackdaws were discovered on a street in Falkoping just before midnight Tuesday.
"Our assessment is that they weren't carrying any contagious disease, but figuring out exactly what did kill them, other than being some sort of external force, is rather outside our area," Olov Andersson, SVA's information officer, told TT news agency.
"What comes to mind is that they may have flown up, and been hit, or something of the sort," he said.
The Local suggested the birds may have been frightened by something in the middle of the night, flown about blindly, and died in collisions with different objects in the dark.
