That is a good reason. I wonder if a Shelduck species would be a good bird for Oceania representation. The Australian and New Zealand species are different, but both are visyally striking and commonish in zoo.I usually put the little blue penguin in an Oceania Pack because it's native to both New Zealand and Australia, which means it counts as an animal towards both (in Australia it's known as the fairy penguin, in NZ it's the little blue penguin or korora).
And we have a serious need of any waterfowl. I'm at the point where I would buy a pack that's five identical wolf subspecies and a duck just for the duck.
