Thank you for the additional info, appreciate it!There is rumor saying that the Planet Zoo II will come up in 2025, with better mechanism that allows the flying birds and aquarium species, we don't have any big change in this game after the Twilight pack probably due to the limit of current mechanism. Nevertheless, that is just a rumor.
I personally also like to see Ground Hornbill, Kakapo and Takahe in the game, but they are very unlikely to be offered.Even Shoebill, one of my favorite birds, can't be guaranteed in the future packs
