Fireworks may have caused Arkansas bird deaths

[Skybird]

Again several hundred birds fell dead from the sky, in Louisianna.

The first bird strike at new years eve was accompanied by a massive dying of fishes in a little river just 150 km away.

The new bird dying took place 600 km south of the first.

If there were volcanoes nearby, I would say volcanic activity and gas intoxication. But so... Anyway, the firwork thoery I do not buy. It would be happening more often, and one would expect the more events the more populated the area is. Which means in the vicinity of major cities birds should not stop falling down form the sky like raindrops there.

Military experiments? Environmental intoxication? Poison garbage? A moving toxic cloud that also is effective when mixing with water?

Events like these are very rare over land, say ornothologists, and another strange thing is why so many birds flocked together - while it is no wandering season.
