This African Grey parrot got out of his cage and was lost outside near Tokyo, Japan. Police rescued the bird and brought it to a veterinary hospital where it recited its name and address to a vet. Through these vocalizations, its owner was located and the bird was returned.http://www.huffingtonpost.com/2008/05/2 ... 02812.html
Nice story huh? This is a really clever idea and it's something useful that everyone might want to try teach their own bird to say. In the event that your bird is lost, this could be helpful if someone finds the bird and is able to locate you.
