Only 4 birds so no lol. Honestly out of this top 20 I would say about 12 are necessary at this point.
Get rid of tree-kangaroo, musk ox, ocelot, markhor, spectacled bear, serval, honey badger, sea otter and gelada (ouch these hurt) and replace them with rhea, scarlet ibis, guineafowl, roadrunner, spider monkey, spoonbill, squirrel monkey, and if we are including manatee screw it include the burrowing owl. And I haven't even included a duck or a pheasant... Yea nevermind this is an impossible task lol.
