How birds have sex…

I’ve been confounded lately about birds and how they have sex.

I’ve looked into it… apparently one bird stands on top of the other bird and furiously rubs its tail feather on the other bird’s tail feather.

I have been unsure about how this is effective. Apparently, birds have one hole, under their tail feather, which slightly protrudes around the edges during mating season.

Upon learning this, I figured the birds would back up to each other and rub their holes together to make the exchange. Alas, that is not how it’s done and I find myself astonished that birds are able to reproduce so prolifically when they are rubbing the tail feathers together instead of the holes.
