The Francois' langur broke free Saturday but was captured after climbing into a eucalyptus tree at a nearby school. The monkey, who is named Chien, was anesthetized by veterinarians and recaptured. Zoo officials said that it is in good condition.
Eucalyptus leaves are poisonous to the langurs, which are native to southeast Asia. Zoo officials are still trying to figure out how the monkey escaped from its cage.
