Yesterday three ducks were swimming on the river closed to each other, then a fourth one came in and landed and disrupted the other three. They all took off right away, but still, the group of three stayed together during the flight, while the fourth one falling behind, tried to join them in mid-air. The three ducks made quick turns, from one side to the other, still really closed together, clearly avoiding the fourth one. After several attempts to join the group of three ducks, the fourth one gave up and made a sharp right turn, and landed on the water by itself. While the other three landed far down the stream.
