The Black throated diver, throughout the breeding season, is a highly territorial bird but every morning at sunrise these birds abandon their territories and seek contact with each other. Their aim is to take part in flockfishing which involves a number of social displays of which the dance is the most conspicous. The film ends with the flock dispersing and they return to their own territories.
