The Visayan warty pig exhibit is bowl-shaped along one side with a concrete mudbank appearance, and a low fence along the visitor side. This enclosure has actually been sitting empty and overgrown with plants for at least a decade, and it was originally an Asian Marsh habitat. That exhibit at one point contained 4 species: Reeve's muntjac, demoiselle crane, mandarin duck and bar-headed goose.
The warty pigs arrived at the start of summer in 2012 but it was a fairly simple reworking of what used to be an Asian marsh exhibit. I do not have any photos of when it held muntjac and waterfowl but that was at least 10 or more years ago. For a decade this enclosure was overgrown and I suspect that the majority of visitors did not even know it was there.
