Sorry to chop up your post like this sis, but I had to respond directly to the actual "meat" irt the OP.
I have read things about a phosgene gas weapon delivered in nano(somethings), to fireworks, to a sonic boom, yadayadyada.
But a low level electromagnetic surge could explain both the birds and the fish.
Being a fisherman myself, I know drum pretty well. Most of them that I catch are in the 2-5 lb range, and I didnt see one over a lb in the dozens of photos. Also some said they are bottom feeders and might have been poisoned. The drum I catch are on LIVE softshelled crawfish, their favorite food.
Also their were hundred of small bass, breem, and rock bass floating in that river as well, so this only lead me to think that it was a constant low level current that did these fish in, rather than a high voltage event which would kill the larger 10-100lb fish as well.
HAARP is most likely responsible for this particular kill as well as the dozens of other occurrences in the latest SIGNS.
