With Nyala moving into the former Tapir exhibit, I can't help but notice this would create an extension of the small African themed zone Melbourne has, following the Giraffes and Baboons.
Whilst the peccaries could still have years ahead of them, it's got me thinking; what African species would be a feasible replacement for them. The one that springs to mind is African Crested Porcupine, who aren't yet held at Zoos Victoria and should be a species of interest. They would fit the current Peccary enclosures quite well with minimal renovations required; and would follow align with the African theming, forming a more consistent trail. Additionally, the multiple exhibits would allow for breeding if that was to be considered.
It would make a lot of sense for the upper section of the Main Trail to be rethemed as an African Trail - with the Savannah and Arid biomes represented. For a greater sense of cohesion, the Lowland nyala should really occupy the old bongo exhibit; as opposed to being in the middle of two Arid exhibits (porcupine and baboons); but since the peccaries could easily have another five years in them, that could be a long term plan.
Cape porcupine don’t make the best display animals outside of a nocturnal setting, but that’s easily remedied by building a small nocturnal viewing hut as an annex off the main exhibit - this serves Hamilton Zoo well at least.
