Even if flying birds aren't possible quite yet, there are still some ground-dwelling birds that could make it into the game. Things like quail, kiwis, and the kakapo. Especially since flightless birds like the kakapo are often endangered. (And of course there's the emu, but I'm wondering if there's an Australian DLC planned....) But yes, even if flying birds aren't quite there yet, please add some more ground-dwelling birds. The species list needs more birds.
