The male who used to be in the house near the Ape House died some time ago - They are entertaining little creatures, especially when they're outside digging at the edge of the water.
I mentioned how that old(?)male used to go back and forth repeatedly along one horizontal branch in stereotyped fashion. I'll bet if you measured the distance you would find it was exactly the same as the width of his cage in the old house. Sad or what?
These are very interesting little monkeys- apparently they are quite closely related to Baboons.
