Here is a list of news letters that Dr Turi wants people to read. Very interesting stuff. Pleas also note that there is an other dead bird issue. Birds falling out of the sky around the world, again!!
It wouldn't be due to Human intervention now would it??. HAARP, Fracking, Chemtrails or some such evil.
It is not natural that is for sure. never in history has there been cases world wide like this, until the 20th Century technology came about. It ain't rocket science. If it harms these poor birds, then what is it doing to us? I think you need to ponder this one people.
