It's getting creepy. First, it was Arkansas, then Louisiana ... now birds are dropping dead out of the skies over Sweden:

To add to the mystery, 50-100 jackdaws, a bird species in the crow family, fell dead in central Sweden late Tuesday night, English-language Swedish news website The Local reported Wednesday.
"We do not know what the cause is," Skovde police commander Tomas Ahlgren said. The birds fell in the city of Falkoping, which is southeast of Skovde.

But conspiracy theorists beware: mass deaths by birds are actually quite common (the US Geological Service's National Wildlife Health Center website listed 90 in the last 6 months alone) and the culprit is usually something mundane: military death ray, er, I mean bacterial infection.
