SAN DIEGO -- A male koala, thought to be in the grip of spring fever, escaped from the koala enclosure at the San Diego Zoo on Tuesday and scampered to a tree several dozen yards away.
The koala was discovered missing about 9 a.m. and was soon found in a nearby tree.
By midafternoon, the 2-year-old koala named Mundu, who was born at the zoo, was still in the eucalyptus tree. Zookeepers were keeping an eye on the animal and plan once the zoo is closed to retrieve him, a spokeswoman said.
"It's that time of year," the spokeswoman said. "He'd like to find a female. This is all about hormones and testing limits."
The zoo has 22 koalas. No zoo patrons were injured in the escape.
