Categories of Animals for Hunting

How would you classify the game available to hunt. I see a lot of different categories and curious what y'all thought. Can only pick 4 for Hunting

Big Game North America, Big game Exotic, small game, predators, upland bird, wingshooting, waterfowl, Big game (native and Exotic), bird hunting.

 

Try explaining that again. I think I'm missing something.

 

Creating a search feature and want people to search animals by categories. Looking to have 4 categories covering big game native and exotic birdhunting and predators. Just trying to find out what most people would expect or want to see when searching for hunting opportunities by animal.
