Some more unsigned species in here: Chestnut-eared finch/Zebra finch, Canary bird, African Jacana, Hottentot teal, Lesser whistling duck, and more.
I actually haven't seen that many other unsigned species the times I've been to the park this year. It actually felt a bit empty when it comes to different kinds of species. You mostly just see canary birds, crowned pigeons, and Nicobar pigeons running around. It's been way richer in different kinds of species before.
