Birds drop dead around the World: Signs?

I watched the news the day before yesterday the story about thousands of birds falling dead from the sky in Arkansas.
Then, yesterday, I watched a news report about the same thing happening, only this time in Sweden. I was a little creeped out.
Today I did a Google search. I was definitely creeped out: More dead birds in Louisiana and Italy.
It is now referred to as a Worldwide Phenomenon.

Experts first proclaimed that the Arkansas deaths where the product of firework scare, but according to this :

Preliminary autopsies on 17 of the up to 5,000 blackbirds that fell on this town indicate they died of blunt trauma to their organs, the state's top veterinarian told NBC News on Monday. Their stomachs were empty, which rules out poison, Dr. George Badley said, and they died in midair, not on impact with the ground.

As for the doves dropping dead in Italy, they had a “a mysterious blue tinge to their beaks”.

This is seriously not funny. I will not even try to make assumptions, but “crushed organs” and “blue beaks”?
It could all mean many things, and none of them good..
To top it all off, this is accompanied by thousands of tons of fish washed up dead on beaches. Can you say Doomsday?
