Tuffy, the male elephant at the Maryland Zoo, sways back and forth almost constantly. Last time I was there, they had a long in his exhibit and he lifted it up with his trunk. However, two minutes later he went back to pacing.
Francois, the male sloth bear at the Smithsonian National zoo also paces. But there's been a sign up for ages telling visitors about this and how the zoo is doing a study on it.
