I know Omaha mixes their pere davids deer with Indian rhinos. It’s an amazing exhibitMoose and Indian rhino sound weird to me... Do their territorial extent even overlap?
I think wild boar would make more sense, especially since it already has enrichments with European cervids and also lives in Asia. People have suggested red panda as well, which would be interesting considering it doesn't have any enrichments so far.
Also, maybe the Japanese raccoon dog could have enrichment with the red-crowned crane?
