@Onychorhynchus coronatus I totally agree. There is some more height to the exhibit, but it is clearly inadequate for Lion-tailed macaques. However, I took this photo a decade ago and there is probably another species in this enclosure now as that type of macaque has become extremely rare in North American zoos.
@snowleopard
They’ve been replaced by a family of black howler monkeys. While not great, this exhibit is far better-suited to howler monkeys as they are smaller and more arboreal than macaques.
