Birds fall dead from the sky worldwide

Hundreds of birds die mysteriously in mid-flight hitting the ground in Cuauhtémoc, 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.
