Birds fall dead from the sky worldwide

Hundreds of birds die mysteriously in mid-flight hitting the ground in CuauhtĂ©moc, Chihuahua, Mexico. 


Another similar incident happened in Pembrokeshire Wales. Around 200 dead or dying starlings fall from the sky and rain down on cars. 

People heard a big flash and loud boom directly after the flash/boom the birds starting falling to the ground. 

And a similar incident happened in Downtown St. Louis where dozens of crows found dead. 

This has been happening for a several of years now and no one has an explanation why birds just drop dead from the sky.
