You haven’t, which is why you have no citation just a ridiculous, unproven anecdote. There are literally hundreds of turbines in my area, there are not and have never been “birds piling up under them.”
Your own link further down estimates 4-18 per year. 1 bird per month would be gone before you had a chance to collect it, much less have a chance to “pile up”.
I am honestly surprised - you should see dead birds at-least a couple of times a week. Not annually or monthly, but weekly esp for a full wind-farm like what you are stating.
Which part of the world do you live in ? It is possible that the location of the farm was chosen wisely. Are you also sure someone is not clearing the corpses ? There are laws mandating the collection of corpses in many western nations. My personal anecdotal opinion is that data is more honest in the non-Western nations since nobody cares about bird-deaths all that much and so the deaths are not sanitized.
The entire US? I’ve been to Hawaii and hiked under turbines, no dead birds. I’ve been hunting in the midwest in fields, no dead birds.
I’ve been hiking in Europe, no dead birds.
Again, where is your citation? If birds are “piling up” they’re should be countless articles on it. Hell BP alone would GLADLY fund studies showing all these birds deaths to justify selling more oil.
