Several Birds Diving Towards Death or Dropping Dead in Mid Flight

With a little research, you will find that these events involving the sudden and inexplicable death of hundreds or even thousands of animals (birds also) are quite common. It's not something from this year or just this decade.
There is evidence that it has been going on for dozens and dozens of years. There are many suspects being highlighted: 5G (which is not a new technology as it has been presented), another weapon of some sort, a militar test, moving of the magnetic field, some Department of Agriculture protecting their product, EMF, Geoengineering chemtrails schemes and the aerosol spraying of our skies, something else alien related, etc.
What is it? I prefer not to speculate...
