I thought it was common knowledge of the bird thing, I have seen it said lots of times in my life.
Its atheists who say it when debating the flood.
I am sure some birds have caught fish and took it to their young in nests on mountain sides.
I believe even dawkins talked about it in a debate, some atheist did just recently on a YT vid debate thing.
Its not ridiculous, its truth in some cases, billions of years and not one bird had a nest on a mountain and brought fish to its young? :sarcastic:
As for the tectonic plates thing, it is not so cut in all cases as you said with the Rockies.
Tons of these pictures show various mountains and how they are formed.
Not all mountains were sea beds at one time.

But, if the ice age is true, all of earth was under froze water at one time.
That accounts for the boulders and fossils, right?
I still dont get why a global flood is so ridiculous to you, you admitted the glacial deposition thing, that takes water melting all over the earth at one time to displace all the millions of boulders scattered everywhere they dont belong.
That is crazy though, for ice to be that huge to carry those huge boulders, that's a lot of ice
