Firstly, congratulations on your pending arrival. Your life will never be the same again.....
Okay, I was going to limit my suggestions to Australian native birds only, but then I figured that I couldn't go past adding Dodo to the list of worst names.
Worst -
Dodo
Galah
Funniest-
Willie Wagtail
Best-
Rosella
We just looked up Rosella. They're very pretty! I think we need to travel more to see those in their natural environment, though.
They are indeed. They only came to mind as we took our 2yo daughter to a Wildlife Sanctuary yesterday where there were a few flying around the trees.
