Out of my field here, But:
Valley exit jet, is a form of jet stream.
Could jet streams be dipping down and cold enough and enough wind speed to kill flying birds?
The weather has been freaky enough world wide to support some
way out speculation.
Reports in now from many countries flocks of dead birds.
But jet streams don't account for dead fish? Do they?
If this is accurate then people caught in the open could be at
risk.
