Not surprising news imo. She was always a 'temporary' replacement following the death of the Mandrills, but I did expect her to be around a little longer as the enclosure was heavily renovated to accommodate her.Just left Melbourne Zoo, Zillie the Cassowary has been moved back into the Great Flight Aviary.
I agree they're the most likely candidates. They suit the rainforest theme, and the enclosure is more than large enough to accommodate a pair of brothers. Obviously more arboreal space would need to be provided, which is something exciting what they do in that case.The old Mandrill/Southern cassowary exhibit could potentially be redeveloped as a Binturong exhibit. No exhibit for them has been announced yet, but there’s more than enough space here to develop an immersive walk through.
