It would be awesome for snowy owls to be brought back they were originally in the Arctic ring of life when it first opened but if I remember correctly the pair ended up getting some sort of disease that sadly resulted in both of there deaths
The Detroit Zoo had a very extensive children zoo in its early years it would make sense for them to try and bring something like that back
Also it’s so depressing seeing an exhibit that used to have a very large heard of guanaco’s so empty and filled with a mismatch of species
