Ah, but humans kill about 7 billion birds a day. So it's a drop in the bucket.

Or so one could reach with Fermi estimates. I think it should be made clear when you link that study that you meant "a back of the envelope calculation says that x birds were killed" etc. etc. rather than implying there was any rigor to it.

Literally making up a number doesn’t support your point, as shown with your wildly incorrect bobcat statement.

And no you can’t reach 7 billion birds a day killed by humans from an honest fermi estimate. People collect information on birds, making wildly incorrect stuff up quickly contradicts actual information which bounds the potential numbers. Feel free to try or actually come up with any actual estimates that support your point.

If it was easy to show this research was wildly inaccurate someone would happily publish a paper showing the errors. You on the other hand are just trying to hand wave I don’t like this therefore it must not be true which is only making you come off as a fool. No, wishing really hard doesn’t make reality bend to your preconceptions.
