After spending a combined 22 years in captivity at the Detroit Zoo, Winky and Wanda the elephants are being freed. The female Asian elephants will be sent to a refuge in Tennessee or California by early fall. Zookeepers felt the climate and small confines were too hard on the elephants. The Detroit Zoo will become the nation's first major animal facility to give away its elephants solely on ethical grounds, according to the Humane Society of the United States. Zoo director Ron Kagan says elephants normally roam 30 miles a day and form strong social bonds with other elephants. They need physical and intellectual stimulation lacking at the zoo.
