Von Frisch studied the waggle dance by training worker bees to syrup feeders at different distances and angles to the hive. He marked foragers with paint dots so that he could recognize them when they returned to their glass-walled observation hive. Many students,colleagues, and his family helped him in his work. He called his discovery the dance language, or Tanzsprache in German. Is it a language like English or German? Not really, as it can only communicate one thing—location. Whether or not it is a true language, the waggle dance is the most complex communication signal found in any animal.
