@Onychorhynchus coronatus No that was the Javan Langur enclosure, aka the former Proboscis Monkey enclosure. I think this space has pretty much always held Silvered Leaf Monkeys and no otters. Some freeflight birds occasionally enter this space, however.
@Onychorhynchus coronatus Yes, otters have not been mixed with the langurs since that incident. The zoo is down to 0.2 very elderly langurs now, though To be replaced with Francois's Langur I believe (at least they are bringing this species in from LA)
