“Faces of the African Forest,” the zoo’s new six-species exhibit on the Tropics Trail, doesn’t officially open until tomorrow. But evening preview events have been going on this week, and yesterday I got a good look at several species: the red river hogs, the West African dwarf crocodiles and, most especially, the black-and-white colobus monkeys.
These guys are gorgeous, with white “capes” and long, fluffy white tails — so gorgeous, in fact, that their fur was used to trim Europeans’ coats in the mid-1800s. (Fortunately, these adaptable leaf-eaters are not endangered.) Their facial structure conveys a perpetual worried frown, just as dolphins always appear to be smiling. Because they have three-chambered “ruminant” stomachs, colobus (pronounced CAHL-a-bus) typically spend most of their day lounging and digesting, but the zoo’s trio still seem intrigued by their new home in the former sun bear exhibit — especially this hollowed-out tunnel log.
In a burst of design brilliance, the log was fashioned so that small humans can crawl through it, with a glassed-in gap in the wood through which the kids and monkeys can see each other. It’s a safe way for children to feel they’re entering the exhibit, even though they’re not. As of yesterday, the monkeys still found this fascinating; at one point, the brothers and their female companion were all leaning over the side of the log to investigate this other species tunneling beneath them.
The monkeys also explored the rear of their exhibit, jumping from tree to tree, capes and tails billowing whitely behind them. (They don’t brachiate with those arms; in fact, “colobus” derives from the Greek word for “mutilated,” meaning these monkeys have ineffective stumps for thumbs.) Also at the rear of the exhibit were our pair of De Brazza’s monkeys and their baby, which I glimpsed only briefly. Smaller and more active than the colobus, the De Brazza’s are expected to become the more entertaining monkey in time. I’ll be waiting to see.
