Jordan Lake. First Nest Victory Duet. Bard is worried because Kate has gone to chase an intruder out of the cove and he also has a fish under his foot he needs to get to his chicks. When a bald eagle couple vanquishes an intruder they often sing a Victory Duet. Bard and Kate sing when Kate returns to the branch. These pairs often throw their heads back, pointing beak straight up and tell the heavens about the victory. Watch Kate literally shake with her song.
