Americans have become pretty stupid.
The primary limiting factor in bird population is and will always continue to be the food supply. There will always be more birds hatched than the food supply can support.
In fact, there will always be more birds hatched that figure out how to not run into windmills or get frickaseed by mirrors than there is enough food for. Additional survival hazards are just changing some of the birds who would have starved into birds who live because a better forager wasn’t clever enough to figure out a hazard.
Its an epic non problem.
Yes. you are right.
And how many birds anyhow? “Dozens over several months”.
That’s certainly less than one a day. Maybe as few as one a week.
