I've heard a few theories but I'm going with a lightening strike. Really interested in tomc's conspiracy theory though.
The corporate greedsters were testing their new weapons on birds before they unleashed them on the middle class proleterians I bet Goldman Sachs invented this new lazer beam killing machine will sell it to the Chinese for Zillions
Not bad Jack, not bad. Waaaaayy too easy. Is Mass Bird and Fish Die Off Connected to Government Testing?
It is actually aliens. The birds sustained the trauma by flying into a force field, the kind found around a space ship. It happens from time to time in various places in the world.
I think we should just take the government's word for whatever happened. I'm sure they'd tell us whatever we needed to know.
That's it. I'm convinced. All these bird deaths in all these locations has to be the result of, what was it, fireworks, last I heard? “The Birds”: Mapping The Global Mass Animal Deaths Graveyard
More fireworks no doubt. That's probably what's responsible for the massive fish kills too. More Dead Birds and Fish Found In Texas & Florida
Rut roh! Crabs now too huh? Damn dangerous fireworks! They should be banned. 40,000 crabs join slew of animal-death mysteries
Let's see..Mass death, birds, fish, crabs, turtle doves, in many states and countries Awwww...c'mon now! No thoughts folks? I'll Say your hymn for you all. "I am lemming, hear me roar, in numbers to big to ignore". Mystery of mass animal death epidemic deepens after 8,000 turtle doves fall dead in Italy with strange blue stain on their beaks Somebody care to offer a different opinion or do I have to do all your thinking for you all?
Fireworks caused the bird deaths, and the contrail off the CA coast was an airplane WTF is going on ?
I think this is kinda like shark attacks. Everyone makes a huge deal when the event is reported but then it always turns out that the occurence isn't really out of the norm. As in tom's link, the crab kill had occured a few times in the past but now, linked with the birds & fish, it becomes another conspiracy. As a kid, I grew up along a river & my Dad just reminded me that a massive kill would happen every few years there. I guess no one ever pinpointed the exact reason for it but toxins from industry, farms, construction etc were always suspected as well as those morons who liked electrocute or blow up the river creatures.
And, of course, underwater UFO bases. Or just go ahead and be a lemming and believe that toxins crap Fox News tries to pass off.
