Considering there were plans for Spotted Hyena; and there is the surplus for them at the moment (unlike with African Wild Dogs), I am interested to see whether Werribee may consider pivoting to Hyenas in the meantime.
I would be surprised. The containment requirements for Spotted hyena are more advanced than what’s required for African wild dogs, which is the reason Hamilton haven’t acquired them yet (the exhibit requires significant upgrades).
It’s unlikely Werribee’s African wild dog exhibit was built to the specifications required for hyena as housing them in that exhibit wasn’t in the plans at the time.
