You apparently are maintaining that the Biblical description of creatures with hollow, bronze bones refers to birds. Which birds have bronze bones. You have conveniently ignored the word bronze since it obviously doesn't mesh with reality. Of course, it just might be possible that this wasn't meant to be taken literally, in which case there's no problem with reconciling any modern scientific theory with the Bible, which was really my point.
"Job 40:18 His bones are as strong pieces of brass; his bones are like bars of iron."
Who said they were hollow?
