Bird mass death, lifeless and dying birds, falling out of the sky, can be toxically, logically, and forensically deciphered and explained.
Chemtrails are many miles long, even covering several grouped adjacent states, simultaneously and have been time-recorded as to lingering for over 20 hours straight.
Migrating bird flocks will have to fly through these toxic, poisonous, oil-coated nanoparticles, all the while directly respiring, filling their lungs thousands of times, continuously, the whole distance and the whole time, both of which are most extensive in miles and hours. All this time the bird flock is getting an oil adhered-to coating of toxic, poisonous, aerosolized nanoparticles, which could soak into the birds bodies and organs and spoil the bird-protective properties of the bird's feathers. Could a human or any living organism, large or small, fly through that same toxins super-smog-laden air and be capable of surviving the toxic oil-coated-nanoparticles without lung-protection or body or wing protection? The answer is no. You would need to don a better than Hepa-rated air-filtered gas mask, which does not exist, yet, due to the super extreme smallness of the bird-flock respired oil- coated toxic metal Oxide ( Al2O3, BaO, SrO) nano particles.
