Titles read: "Voices! Whenever "eats" are close at hand, nature has its own way of welcoming the moment. For instance, the Swan Song - ".
Location of events unknown - probably United States of America.
Various shots of a man feeding a flock of swans on a river. We then see numerous monkeys in a cage, squawking and gathering around a barrel of food. They scramble madly to get through an door in their cage; intertitle says it is worse than the rush for the last tram or bus.
