Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 

 

Here and there in that palace were multitudes of live swans and pigeons, as well as artificial swans and pigeons so lifelike that the real swans rose above them again and again, thinking them live birds like themselves. Thus the palace vibrated with the sounds of these birds.
