Bird deaths on a massive scale

[kdog]

I wonder how it correlates with the rollout of 5G? 5G is microwaves, like radar, and I've seen radar powerful enough to flash-fry birds that flew through the beam.

And/or the weakening of the Earth's magnetic field - how might that impinge on the bird die-offs?

Fluctuations of the Earth's magnetic  field could cause confusion in birds, as well as marine mammals.
