The funniest thing about this is that my comment wasn't meant to be serious hahaWhy does the ibis suggestions always turn into this? Just agree to disagree.
I do prefer them as habitat animals ofc and the fact that they are kept or not exclusively in aviaries in the real world doesn't really matter because: 1. Is a game and you can play however your imagination or creativity allows you to 2. You can build piece by piece aviaries in the game for habitat birds/primates anyway and 3. You can delete all the walls of the WTE so you can even turn then into open habitats.
What animals that are chosen for the WTE is based on how their particular locomotion is not fit for the regular habitats with current Game mechanics. And considering that ibises do work as habitat birds that's why i said (kind of jokingly BTW) that wanting them for the WTE was crazy.
And on top of all that i like the WTE. I have always liked them and defend their inclusion in the game and even with it's limitations (like size and straight path) i've seen people do awesome things with them. So if ibises come in the WTE and the do fly and perch then they are more than welcome in that way, but we know they can work perfectly fine as habitat birds as well.
