Measuring both on Google Maps, Brookfield's exhibit is slightly larger. This exhibit may be longer, but it is also significantly shallower of an exhibit. Brookfield's exhibit: 0.075 acres, Detroit's exhibit: 0.069 acres.It looks larger than the grottos at Brookfield Zoo Chicago, which I guess isn't really saying much but it wouldn't be the worst for either species. I don't remember where this is in the zoo from my single visit though, so I don't know if the picture is misleading.
And I definitely think "Detroit's standards for other megafauna" is a big key here. While this exhibit may be perceived as a slightly outdated bear exhibit at a different zoo, but given the high standards at Detroit it'd stand out as easily one of the worst exhibits at the zoo. Perceptions matter, and it is easy for someone to leave a zoo with a bad taste in their mouth purely due to one exhibit they didn't like, even if the rest of the zoo was excellent.I think it looks a bit big for something like a coati or a porcupine but definitely wouldn't fit with Detroit's standards for other megafauna.... grotto-style exhibits are out for cats and bears but tend to be a poor fit for smaller species in my experience. Look forward to finding out what goes there.
The grottos at Brookfield don't stand out as overly bad because the rest of the zoo similarly contains some dated sections, the same can not be said about Detroit, which maintains some of the largest and most modern exhibits in the AZA for many of their species.
Even if it housed bears historically doesn't mean it is acceptable to house bears again. I would be absolutely SHOCKED if this exhibit became home to sloth bears, or any megafauna for that matter.It’s not that small of an habitat, in recent years it held, black bears, red pandas and most recently a grizzly bear. I’m not sure what we may get but I still think the sloth bear is a possibility.
