Bennett's Wallabies are one of the most common small mammals to see in US Zoos. However, other Wallaby species seem to be few and far between. Tammars are certainly out there at a few facilities, and Parma, Swamp, and Yellow-spotted Rock Wallabies at a minimum are all present in even smaller numbers. Unfortunately, it doesn't seem like any of the non-Bennett's Wallabies are around in large numbers, which is a real shame in my opinion, as they are some really awesome species, many of which I'd say are cuter than the ubiquitous Bennett's Wallabies. Is an increase of non-bennett's wallabies in US Zoos foreseeable, or even feasible? I sure hope that keeping multiple Wallaby species in US Zoos stays a reality, but it looks like that may not be the case for much longer. What Wallaby species other than Bennett's may remain in the US long-term, given current trends in US Zoo populations?
