Over at ENWorld, someone, called Echohawk, has listed all of the OD&D, AD&D and 2nd edition AD&D creatures that haven't been converted to 3rd edition yet. He has done this in a single thread (for all D&D campaign settings) on their forums, but has also broken the information down into individual campaign settings. According to him there are 24 Birthright monsters and 34 unique Birthright creatures that haven't been done yet.

I was wondering if anyone wanted to help get some of them converted and put onto Birthright.net. Here is the stuff he says needs doing:

I wouldn't normally post links to other forums, but in this case, I think this project could be helpful to the Birthright community, so I hope the mods don't mind. Here are the two threads:
Total number of unconverted D&D creatures
Unconverted Birthright creatures

If any mods have ENWorld accounts, it might be nice if you could pop over and say hello.
